I-SelerUlose Ether yi-polymer ye-ionic ye-unic ye-unic ye-unic ye-unic ye-unic ye-unic ye-unic ye-semi-inyibilikisi kwaye inyibilikiswe ngamanzi. Ineziphumo ezahlukeneyo kumashishini ahlukeneyo. Umzekelo, kwizinto zokwakha iikhemikhali, ineziphumo ezihlanganisiweyo zilandelayo:
I-Arhente yokugcina amanzi
②thickener
③level
Ukuqulunqwa kwe-④Film
⑤ Binder
Kwishishini le-polyvinyl pherviny, sisimo esouressifier kwaye sisasazeke; Kumzi-mveliso wamachiza, yindawo yokubhabha kunye ne-Spof Stores, ilawulwa, njl njl. Okulandelayo, ndiza kugxila ekusetyenzisweni kunye nomsebenzi we-selsulose ether kwizinto ezahlukeneyo zokwakha.
I-1. Kwishishini lepeyinti le-testx, khetha i-hydroxyylyl seluplose, inkcazo ngokubanzi ye-vircofity ilinganayo yi-HB350-500CP, ehambelana ne-HBB250CEP, ehambelana ne-Hossage ye-HIB250, kwaye i-Desalad i-1.5 ‰ -2 ‰. Umsebenzi ophambili we-hydroxyythl kwipeyinti ye-Latex yeyokuthintela i-pigment, nceda ukusasazeka kwe-pigment, uncede ukusasazeka kwe-pigment, uzinzo lwe-Latex, kwaye unyuse ukugqitywa kwenqanaba lokwakhiwa : I-HydroxyEtheetheetheetheetheetheetheetheetheetheethes ilula ukuyisebenzisa. Ingachithwa kumanzi abandayo okanye amanzi ashushu, kwaye ayichaphazeleki lixabiso le-pH. Ingasetyenziswa ngokukhuselekileyo phakathi kwexabiso le-PI 2 ne-12. Iindlela zokusetyenziswa yile ilandelayo:
I. Yongeza ngokuthe ngqo kwimveliso: kule ndlela, i-hydroxyythl seluplose yeselfowuni kufuneka ikhethwe, kwaye i-hydroxytethy yexesha elingaphezulu kwemizuzu engama-30 lisetyenziswa. Amanzi amancinci acocekileyo ngaphakathi komlomo ②start axhuma ngesantya esisezantsi ngokuqhubekayo, kwaye kwangaxeshanye ayongeza i-③continueds kunye ne-Alstitives ye-GADSE i-③stimus kunye neqela le-hydroxyyl Ichithwe ngokupheleleyo, yongeza amanye amacandelo kwifomula, kunye nokugaya kude kube yimveliso egqityiweyo.
Ⅱ. Ixhotywe ngotywala bukamama ukuba isetyenziswe kamva: Le ndlela inokukhetha i-seluplose yethutyana, enefuthe lokuphononongwa. Inzuzo yale ndlela kukuba iguquguqukele ngakumbi kwaye inokutongelwa ngokuthe ngqo kwipeyinti ye-Latex. Indlela yokulungiselela iyafana namanyathelo ①-④.
Ⅲ. Lungiselela i-Porridge yokusetyenziswa kamva: Ekubeni izinyibilikisi zendalo zizinto ezinqabileyo (i-insullen) ye-hydroxyyteythl, ezi zinyibilikisi zinokusetyenziselwa ukulungisa i-porridge. Ezona zigqibo zisetyenziswayo zisetyenziswayo zisetyenziswayo zizinto eziphilayo ze-organic kwindawo yokupeyinta i-FEELX, ezinje nge-ithylene glycol, i-propylene glycol, kunye neearhente zefilimu (ezinjengee-dizylene glyl suttate). I-Porridge ye-Holdroxythyl isellise inokulongezwa ngokuthe ngqo kwipeyinti. Qhubeka nokuvuselela kude kukhanyeswe ngokupheleleyo.
2. Kwi-Udol Skutty: Okwangoku, ukukhusela okusingqongileyo i-Isty enganyangekiyo ngamanzi kunye nokunganyangeki kwamanzi kwizixeko ezininzi kwilizwe lam. Impilo, iglue ye-glue yenziwa nge-polyvinyl utywala kunye ne-foraldehydehyde. Ke ngoko, le nto ishenxiswa ngabantu, kwaye i-Sersuse Ether Erise Series isetyenziselwa ukutshintsha olu phawu. Oko kukuthi, ukuphuculwa kwezinto zokwakha ezinobuhlobo bokusingqongileyo, i-sellyuese okwangoku kuphela kwezinto. Kwindlela enganyangekiyo yamanzi, yahlulwe yangamacala amabini: i-powder eyomileyo ayinamathisi. Phakathi kwezi ntlobo zimbini ze-ifatty, ezilungisiweyo ze-methyl ye-melsulose kunye ne-hydroxypropy ye-methyl kufuneka ikhethwe. I-Viscofity Ingcaciso ngokubanzi phakathi kwe-30000-600cps. Imisebenzi ephambili ye-itlulose e-Ittty yindawo yokugcina amanzi, i-bonds kunye ne-thabrication. Kuba ifomula ye-putty yabavelisi abahlukeneyo zahlukile, ezinye zii-calcium engwevu, i-calcium yokukhanya, isamente emhlophe, njl njl, njl njl. Iifomula ezimbini zahlukile. Isixa esongeziweyo simalunga ne-2 ‰ -3 ‰. Ekwakhiweni kwendlela yokubeka i-wall, kuba umhlaba osisiseko udonga lunomgangatho othile wokufumana amanzi Ukudityaniswa nokuphuma kwehlabathi elingaphandle, ukuba i-DOTTY iphulukana namanzi ngokukhawuleza, iya kukhokelela kwi-rocks okanye i-powder esuswe, ethi ibonakalise amandla ka-Uty. Ke ngoko, ukongeza i-ilesese i-ether kuya kuyisombulula le ngxaki. Kodwa umgangatho we-filler, ngakumbi umgangatho we-Ash Calcium nako kubaluleke kakhulu. Ngenxa ye-viscosity ephezulu yeselselose, i-Buoyisay ye-ITTY iphuculwe, kwaye i-Shenomen etyhafileyo iphinde yathintelwa, kwaye ikhululekile kakhulu kwaye ikhuselekile ekusebenzeni. Kulungele ukongeza i-seluplose ether kwi-powder itoty. Ukuveliswa kwayo kunye nokusetyenziswa kwayo kulula ngakumbi. I-fililler kunye nezongezo zinokudityaniswa ngokucacileyo kwi-powder eyomileyo.
3. Udaka lwekhonkrithi: kwi-Corirte Thictor, ukufezekisa amandla, isamente kufuneka ihlanjwe ngokupheleleyo. Ngakumbi ukwakhiwa kwehlobo, udaka lwekhonkrithi luphulukana namanzi ngokukhawuleza, kwaye amanyathelo o-hydration ogqityiweyo asetyenziselwa ukugcina nokutshiza amanzi. Indlela yokuqala kukubangela inkunkuma yezixhobo zamanzi kunye nokusebenza okungahambelaniyo. Inqaku eliphambili kukuba amanzi aphezulu, kwaye i-hydication yangaphakathi ingaphelelanga. Ke ngoko, isisombululo sale ngxaki kukudibanisa ii-arhente zokugcina amanzi asibhozo kwikhonkrithi. Ngokubanzi, i-Hydroxyl ikhethiwe. I-methyl okanye i-methyl sellyulose, i-viscofity yegama elibonakalayo liphakathi kuka-20000-60000cps, kunye nexabiso elongeziweyo yi-2% -3%. Ireyithi yokugcina amanzi inokunyuswa ngaphezulu kwe-85%. Indlela yokusetyenziswa kwikhonkrithi yekhonkrithi kukudibanisa umgubo owomileyo ngokulinganayo kwaye uthule emanzini.
I-4. Kwi-fricking gypsum, i-Bypsum yeGypsum, kunye ne-gulking gypsum: Ngophuhliso olukhawulezileyo lweshishini lokwakha, imfuno yabantu yezinto zokwakha ezitsha iyanda. Ngenxa yokwanda kokwaziswa kwabantu kukhuseleko lwendalo kunye nokuphuculwa okuqhubekayo kokusebenza ngokukuko, izixhobo ze-Gypsum zeGypsim ziye zaphuhliswa ngokukhawuleza. Okwangoku, ezona ntlobo ziqhelekileyo ze-gypsum zifihla i-gypsum, i-godpsum ye-godpsum, i-insiid gypsum, kunye ne-tile. Ukupaka i-gypsum yinto ephakathi yokubekwa phantsi kweendonga zangaphakathi kunye nophahla. Umphezulu wodonga uphakanyisiwe kwaye kulungile kwaye kulungile. Ibhodi entsha yokwakha iBhodi yeBhodi yeBhodi ye-Adhengive yindawo enamathele e-Gypsim njengezixhobo ezisisiseko kunye nezixhobo ezahlukeneyo. Ilungele ukoyikwa phakathi kwezinto ezahlukeneyo zodonga. Ayisiyo inetyhefu, amandla e-odor, kwangoko kunye nokumiswa ngokukhawuleza, ukuxhobisa okuqinileyo kunye nezinye iimpawu, zizinto ezixhasayo zokwakha iibhodi zebhlokhi kunye nokwakhiwa kwebhloko; Iarhente ye-Gyppum ye-Gyppum ngumzili we-filler filler phakathi kweebhodi ze-gypsim kunye nokulungisa i-filler yedonga kunye neendonga. Ezi mveliso ze-gypsim zinothotho lwemisebenzi eyahlukeneyo. Ukongeza kwindima ye-gypsim kunye neefilimu ezinxulumene noko, umba ophambili kukuba i-Seatheritives eyongezelelweyo idlala indima ekhokelayo. Kuba i-gypsum yahlulwe yaba yi-anhydaral gypsum kwaye i-hemimdrate gypsum, i-gypsum eyahlukileyo ineziphumo ezahlukeneyo kwimveliso, i-curing, ukugcinwa kwamanzi, ukugcinwa kwamanzi kunye nokubuyiselwa komhlaba. Ingxaki eqhelekileyo yezi zixhobo ikhutshiwe kwaye ikhwele, kwaye amandla okuqala akanakufikelelwa. Ukusombulula le ngxaki, kukukhetha uhlobo lwesellulose kunye nendlela yokusetyenziswa kwesixhobo sokuhlala. Kule meko, i-methyl okanye i-hydroxypropyl methyl i-30000 inyuliwe. -60000cps, isixa esongezelelweyo yi-1.5% -2%. Phakathi kwawo, I-SellUlose igxile ekugcinweni kwamanzi kunye nokubuyisa i-oyile. Nangona kunjalo, akunakwenzeka ukuba ixhomekeke kwi-ether sether njenge-restarder, kwaye kuyanyanzeleka ukongeza i-cicric rearder ukuxuba kunye nokusetyenziswa ngaphandle kokuchaphazela amandla okuqala. Ukugcinwa kwamanzi ngokubanzi kubhekisa ukuba amanzi amaninzi azakulahleka ngokwemvelo ngaphandle kokufunxa kwamanzi angaphandle. Ukuba udonga luyomile kakhulu, ukufunxa kwamanzi kunye nokuphuma kwendalo kumphezulu wendalo kuya kwenza ukuba izinto ziphulukane namanzi ngokukhawuleza, kwaye ukuqhekeza kwaye ukonakala kwaye kuyakwenzeka. Le ndlela yokusetyenziswa ixutywe nomgubo owomileyo. Ukuba ulungiselela isisombululo, nceda ujonge kwindlela yokulungiselela yesisombululo.
I-5. Ukufakelwa kwe-insursern therrths luhlobo olutsha lwezinto ezingaphakathi kwi-insumpations kwingingqi esemantla. Yinto eyenziwe ngodonga olwenziwe sisixhobo sokufakwa, udaka kunye ne-binder. Kule nto, i-seluplose idlala indima ephambili ekwenzeni nasekukhuliseni amandla. Ngokukodwa khetha i-methyl seluplose nge-viscosity ephezulu (malunga ne-10000s), idosi ngokubanzi phakathi kwe-2 ‰ -3 ‰), kwaye indlela yokusetyenziswa ngumgubo owomileyo.
I-6. I-ampant storment Khetha i-HPNN HPS ye-HPSN AMERE Isetyenziswe njengearhente yokugcina amanzi kwi-thayile yokuthintela iithayile kwi-diledy ngokukhawuleza kwaye iwele.
