I-viscosity ephantsi: i-400 isetyenziselwa udaka oluzimeleyo, kodwa luthunyelwa ngokubanzi.
Isizathu: I-viscosity ephantsi, ukugcinwa kwamanzi kakubi, kodwa iipropathi ezilungileyo zokulinganisa, ubuninzi bodaka oluphezulu.
I-viscosity ephakathi kunye nephantsi: i-20000-40000 isetyenziselwa ngokukodwa ukunamathela kwi-tile, i-agent agent, i-anti-crack mortar, i-thermal insulation bonding mortar, njl.
Izizathu: Ukusebenza kakuhle, amanzi amancinci ongeziweyo, kunye nokuxinana okuphezulu kodaka.
1. Loluphi usetyenziso oluphambili lwe-hydroxypropyl methylcellulose (HPMC)?
——A: I-HPMC isetyenziswa kakhulu kwizinto zokwakha, iingubo, iintlaka zokwenziwa, iiseramikhi, amayeza, ukutya, amalaphu, ezolimo, izithambiso, icuba kunye namanye amashishini.I-HPMC inokohlulwa ibe: ibakala lokwakha, ibakala lokutya kunye nebakala loxubo-mayeza ngokwemigaqo yokusetyenziswa.Okwangoku, uninzi lweemveliso zasekhaya zikumgangatho wokwakha.Kwibakala lokwakha, i-putty powder isetyenziswe kwisixa esikhulu, malunga ne-90% isetyenziselwa i-putty powder, kwaye intsalela isetyenziselwa udaka lwesamente kunye neglue.
2. Zingaphi iindidi ze-hydroxypropyl methylcellulose (HPMC) ezikhoyo?Ziziphi iindlela abazisebenzisayo?
——A: I-HPMC inokohlulwa ibe uhlobo olukhawulezileyo kunye nohlobo olunyibilikayo olushushu.Iimveliso ezikhawulezayo zisasazeka ngokukhawuleza emanzini abandayo kwaye zinyamalale emanzini.Ulwelo akukho viscosity ngeli xesha kuba HPMC uchithachitheke kuphela emanzini kwaye hayi ngokwenene kunyibilike.Emva kwemizuzu emi-2, i-viscosity ye-liquid iyanda ngokuthe ngcembe kwaye i-colloid ebonakalayo ebonakalayo yenziwa.Iimveliso ezishushu ezinyibilikayo zinokusasazeka ngokukhawuleza emanzini ashushu kwaye zinyamalale emanzini ashushu xa zidibana namanzi abandayo.Xa amaqondo obushushu ehla ukuya kubushushu obuthile (imveliso yenkampani yethu ngama-65 ngokukaCelsius), i-viscosity ibonakala ngokucothayo de yenziwe i-viscous colloid ecacileyo.Uhlobo olushushu olunyibilikayo lungasetyenziselwa kuphela umgubo weputty kunye nodaka.Kwiglue yolwelo kunye nepeyinti, i-clumping iya kwenzeka kwaye ayinakusetyenziswa.Uhlobo lwangoku lunoluhlu olubanzi lwezicelo.Ingasetyenziselwa i-putty powder, udaka, iglue engamanzi, kunye nepeyinti ngaphandle kokuchasana.
3. Ziziphi iindlela zokunyibilikisa i-hydroxypropyl methylcellulose (HPMC)?
——Impendulo: Indlela yokuchithwa kwamanzi ashushu: Ekubeni i-HPMC inganyibiliki emanzini ashushu, i-HPMC inokusasazwa ngokulinganayo kumanzi ashushu kwinqanaba lokuqala kwaye inyibilike ngokukhawuleza emva kokupholisa.Iindlela ezimbini eziqhelekileyo zichazwe ngezantsi:
1) Beka umlinganiselo ofunekayo wamanzi ashushu kwisikhongozeli kwaye ufudumale ukuya kuma 70℃.Yongeza kancinci i-hydroxypropyl methylcellulose ngokushukumisa kancinci.Ekuqaleni i-HPMC idada phezu kwamanzi, emva koko yenze i-slurry, kwaye ipholile ngokuvuselela.
2).Yongeza i-1/3 okanye i-2/3 yomthamo ofunekayo wamanzi kwisitya, ushushu ukuya kwi-70 ° C, usasaze i-HPMC ngokwendlela ye-1), kwaye ulungiselele udaka lwamanzi ashushu;uze ungeze inani eliseleyo lamanzi abandayo kwi-slurry yamanzi ashushu.i-slurry emanzini, xuba kwaye upholise umxube.
Indlela yokuxuba umgubo: Xuba i-HPMC yomgubo kunye nesixa esikhulu sezinye izinto ezinomgubo, xuba ngokucokisekileyo kunye ne-blender, uze udibanise amanzi ukuze unyibilike.Ngeli xesha, i-HPMC inokuchithwa kwaye ayiyi kuhlanganisana, kuba kukho i-HPMC encinci kwisahlulo ngasinye.Ikona encinci.Umgubo unyibilika ngokukhawuleza xa udibana namanzi.——I-Putty powder kunye nabavelisi bodaka bamkela le ndlela.IHydroxypropyl methylcellulose (HPMC) isetyenziswa njenge-thickener kunye ne-agent egcina amanzi kwi-putty powder mortar.
4. Indlela yokugweba umgangatho we-hydroxypropyl methylcellulose (HPMC) ngokulula kunye ne-intuitively?
——Impendulo: (1) Ubumhlophe: Nangona ubumhlophe abunakugqiba ukuba ngaba i-HPMC kulula ukuyisebenzisa, ukuba izikhanyisi zongezwa ngexesha lenkqubo yokuvelisa, iya kuchaphazela umgangatho wayo.Nangona kunjalo, uninzi lweemveliso ezilungileyo zinobumhlophe obuhle.(2) Ukulunga: Ukulunga kwe-HPMC ngokuqhelekileyo yi-80 mesh kunye ne-100 mesh, kunye ne-120 mesh ibe ngaphantsi.Uninzi lwe-HPMC eveliswe e-Hebei yi-80 mesh.Okona kucolekileyo kokukhona kungcono.(3) Ukuhanjiswa kokukhanya: Faka i-hydroxypropyl methylcellulose (HPMC) emanzini ukwenza i-colloid ebonakalayo, kwaye ukhangele ukukhanya kwayo.Ukuphakama kokuhanjiswa kokukhanya, kungcono, kubonisa ukuba kukho izinto ezincinci ezinganyibilikiyo ngaphakathi.Ukungena komoya kwereactors ezithe nkqo ngokuqhelekileyo kungcono kune reactors ezithe tyaba, kodwa akunakutshiwo ukuba umgangatho wereactors eme nkqo ungcono kunolowo weereactor ezixwesileyo.Kukho izinto ezininzi ezimisela umgangatho wemveliso.(4) Umxhuzulane okhethekileyo: Okukhona mkhulu umxhuzulane othile kunye nobunzima, kokukhona ungcono.Ubunzima obuthile ngokuqhelekileyo bubangelwa umxholo ophezulu we-hydroxypropyl kuwo.Ukuphakama komxholo we-hydroxypropyl, ngcono ukugcinwa kwamanzi.
5. Yiyiphi i-dosage ye-hydroxypropyl methylcellulose (HPMC) kwi-putty powder?
——Impendulo: Umthamo we-HPMC kwizicelo ezichanekileyo uyahluka ngokwemozulu, ubushushu, umgangatho wekhalsiyam yothuthu lwendawo, kunye nefomula yokufaka.umgubo kunye "nomgangatho ofunwa ngumxhasi".Ngokuqhelekileyo, iphakathi kwe-4kg kunye ne-5kg.Ngokomzekelo, uninzi lwe-putty powder eBeijing yi-5 kg;uninzi lwe-putty powder eGuizhou yi-5 kg ehlotyeni kunye ne-4.5 kg ebusika;
6. Yintoni i-viscosity efanelekileyo ye-hydroxypropyl methylcellulose (HPMC)?
——Impendulo: I-Putty powder ixabisa i-yuan eyi-100,000, kwaye udaka lufuna ngaphezulu, ngoko ke i-yuan eyi-150,000 yanele.Kwaye owona msebenzi ubalulekileyo we-HPMC kukugcinwa kwamanzi, kulandelwa ukutyeba.Kwi-putty powder, nje ngokuba inokugcinwa kakuhle kwamanzi kunye ne-viscosity ephantsi (70,000-80,000), ilungile.Ngokuqinisekileyo, ukuphakama kwe-viscosity, ngcono ukugcinwa kwamanzi okuhambelanayo.Xa i-viscosity idlula i-100,000, i-viscosity inefuthe elincinci ekugcinweni kwamanzi.
7. Ziziphi iimpawu eziphambili zezobugcisa ze-hydroxypropyl methylcellulose (HPMC)?
——A: Umxholo weHydroxypropyl kunye ne-viscosity, uninzi lwabasebenzisi banenkxalabo malunga nezi zalathisi zibini.Ukuphakama komxholo we-hydroxypropyl, ngcono ukugcinwa kwamanzi.Nge-viscosity ephezulu, ukugcinwa kwamanzi ngokulinganayo (kungekhona ngokupheleleyo) kungcono, kwaye kunye ne-viscosity ephezulu, isetyenziswe kangcono kwi-samente mortar.
8. Ziziphi ezona zixhobo ziphambili ze-hydroxypropyl methylcellulose (HPMC)?
—— A: Izinto eziphambili ze-hydroxypropyl methylcellulose (HPMC): i-cotton ecocekileyo, i-methyl chloride, i-propylene oxide, ezinye izinto ezisetyenziswayo ziquka i-caustic soda, i-asidi, i-toluene, i-alcohol isopropyl, njl.
9. Yiyiphi indima ephambili ye-HPMC ekusebenziseni i-putty powder?Ingaba inazo naziphi na iziphumo zekhemikhali?
——Impendulo: I-HPMC inemisebenzi emithathu emikhulu yokuqina, ukugcinwa kwamanzi kunye nokwakhiwa kwiputty powder.Ukuqina: Iselulosi inokujiya ukunqunyanyiswa, gcina iyunifomu yesisombululo kwaye uxhathise ukudodobala.Ukugcinwa kwamanzi: Yenza i-putty powder yome kancinci kwaye uncedise ukuphendula kwe-calcium engwevu phantsi kwesenzo samanzi.Ukwakhiwa: I-Cellulose inefuthe lokuthambisa kwaye inokwenza i-putty powder ibe nokusebenza kakuhle.I-HPMC ayithathi nxaxheba kuyo nayiphi na intshukumo yeekhemikhali kwaye idlala indima encedisayo kuphela.Xa i-putty powder yongezwa emanzini kwaye isetyenziswe eludongeni, ukusabela kweekhemikhali kuya kwenzeka.Njengoko kusenziwa into entsha, i-putty powder eludongeni iyasuswa eludongeni kwaye igaywe ibe ngumgubo ngaphambi kokusetyenziswa.Oku akusebenzi kuba into entsha (calcium carbonate) yenziwe.) phezulu.Amacandelo aphambili e-gray calcium powder ngala: umxube weCa(OH)2, iCaO kunye nexabiso elincinci leCaCO3, CaO+H2O=Ca(OH)2 -Ca(OH)2+CO2=CaCO3↓+H2O Grey calcium inyibilika emanzini nasemoyeni CO2 Ngaphantsi kwesenzo se-calcium carbonate, i-HPMC igcina amanzi kuphela kwaye incedisa i-calcium engwevu ukuba iphendule kakuhle, kwaye ayithathi nxaxheba kuyo nayiphi na impendulo ngokwayo.
10. I-HPMC yi-ether ye-cellulose engekho i-ionic, ngoko ke yintoni i-non-ionic?
IMPENDULO: Ngokwemigaqo ye-layman, ii-non-ion zizinto ezingenzi i-ayoni emanzini.Iionization yinkqubo apho i-electrolytes yahlukanayo ibe yi-ion ehlawulwa ngokukhululekileyo kwizinyibilikisi ezithile (umz., amanzi, utywala).Ngokomzekelo, i-sodium chloride (NaCl), ityuwa esetyenzisiweyo yonke imihla, inyibilika emanzini kunye ne-ionizes, ivelisa ngokukhululekileyo i-ion ye-sodium ehlaziywa ngokukhululekileyo (Na +) kunye ne-ioni ye-chloride (Cl).Oko kukuthi, xa i-HPMC ifakwe emanzini, ayidibanisi kwii-ion ezihlawuliswayo, kodwa ikhona kwifom ye-molecular.
