I-putty powder luhlobo lwezinto zokuhlobisa izakhiwo, amacandelo aphambili yi-talcum powder kunye neglue. Umaleko omhlophe kumphezulu wegumbi elingenanto elisanda kuthengwa yi-putty. Ngokuqhelekileyo ubumhlophe be-putty bungaphezu kwe-90 ° kwaye ukucoleka kungaphezulu kwe-330 °.
I-Putty luhlobo lwezinto ezisisiseko ezisetyenziselwa ukulungiswa kweendonga, ezibeka isiseko esihle kwisinyathelo esilandelayo sokuhlobisa (ukupenda kunye nephepha lodonga). I-Putty yohlulwe ibe ziindidi ezimbini: i-putty yangaphakathi eludongeni kunye ne-putty eludongeni lwangaphandle. I-putty yodonga lwangaphandle inokuxhathisa umoya kunye nelanga, ngoko ine-gelation efanelekileyo, amandla aphezulu kunye nesalathisi esisingqongileyo esiphantsi. Isalathiso esibanzi se-putty eludongeni lwangaphakathi lulungile, kwaye lucocekile kwaye lunobume bendalo. Ngoko ke, udonga lwangaphakathi alukho ukusetyenziswa kwangaphandle kwaye udonga lwangaphandle alukho ukusetyenziswa kwangaphakathi. Iiputty zihlala zisekwe kwigypsum okanye kwisamente, ngoko ke iindawo ezirhabaxa kulula ukuzibophelela ngokuqinileyo. Nangona kunjalo, ngexesha lokwakha, kusafuneka ukuxubha umaleko we-agent ye-interface kwisiseko ukutywina isiseko kunye nokuphucula ukunamathela eludongeni, ukwenzela ukuba i-putty ikwazi ukubophelela ngakumbi kwisiseko.
Abasebenzisi abaninzi be-putty powder kufuneka bavume ukuba ukuchithwa kwe-putty powder kuyingxaki enkulu kakhulu. Kuya kubangela ukuba ipeyinti ye-latex iwele, kunye nokuqhaqha kunye nokuqhekeka kwe-putty layer, eya kubangela ukuqhekeka kwipeyinti yepeyinti ye-latex.
I-De-powdering kunye nomhlophe we-putty powder okwangoku zezona ngxaki zixhaphakileyo emva kokwakhiwa kwe-putty. Ukuqonda izizathu ze-putty powder de-powdering, kufuneka siqale siqonde amacandelo ezinto ezisisiseko kunye nemigaqo yokuphilisa ye-putty powder, kwaye emva koko udibanise umphezulu wodonga ngexesha lokwakhiwa kwe-putty Ukomisa, ukufunxa kwamanzi, ubushushu, ukoma kwemozulu, njl.
8 izizathu eziphambili zokuwa kweputty.
isizathu esinye
Amandla okudibanisa i-putty akwanele ukuba abangele ukukhutshwa komgubo, kwaye umenzi unciphisa iindleko ngokungaboniyo. Amandla okudibanisa i-powder ye-rubber ayinzima, kwaye inani lokongezwa lincinci, ngakumbi kwi-putty yodonga lwangaphakathi. Kwaye umgangatho weglue unento eninzi yokwenza kunye nemali eyongeziweyo.
Isizathu sesibini
Ifomula yoyilo olungenangqiqo, ukhetho lwezinto eziphathekayo kunye neengxaki zesakhiwo zibaluleke kakhulu kwi-putty formula. Ngokomzekelo, i-hydroxypropyl methylcellulose (HPMC) isetyenziswe njenge-putty engenamanzi yodonga lwangaphakathi. Nangona i-HPMC ibiza kakhulu, ayisebenzi kwiifayili ezifana ne-double fly powder, i-talcum powder, i-wollastonite powder, njl. Ukuba kuphela i-HPMC isetyenzisiweyo, iya kubangela i-delamination. Nangona kunjalo, i-CMC kunye ne-CMS enamaxabiso aphantsi ayisusi i-powder, kodwa i-CMC kunye ne-CMS ayinakusetyenziswa njenge-putty engenamanzi, kwaye ayinakusetyenziswa njenge-putty yangaphandle eludongeni, kuba i-CMC kunye ne-CMS isabela nge-gray calcium powder kunye ne-samente emhlophe, eya kubangela delamination. Kukwakho i-polyacrylamides eyongezwe kwi-lime calcium powder kunye ne-samente emhlophe njengezinto zokugquma ezingangeni manzi, eziya kubangela ukusabela kweekhemikhali kubangele ukususwa komgubo.
Isizathu sesithathu
Ukuxuba okungafaniyo kusona sizathu siphambili sokukhutshwa kwepowder kwi-putty ngaphakathi kunye neendonga zangaphandle. Abanye abavelisi kweli lizwe bavelisa i-putty powder kunye nezixhobo ezilula kunye nezahlukeneyo. Azikho izixhobo ezikhethekileyo zokuxuba, kwaye ukuxuba okungafaniyo kubangela ukukhutshwa kwepowder of putty.
Isizathu sesine
Impazamo kwinkqubo yokuvelisa ibangela ukuba i-putty ibe ngumgubo. Ukuba umxube awunawo umsebenzi wokucoca kwaye kukho iintsalela ezininzi, i-CMC kwi-putty eqhelekileyo iya kusabela nge-ash calcium powder kwi-putty engenamanzi. I-CMC kunye ne-CMS kwi-putty eludongeni lwangaphakathi kunye nodonga lwangaphandle I-samente emhlophe ye-putty isabela ukuze ibangele i-powdering. Izixhobo ezikhethekileyo zeenkampani ezithile zixhotyiswe ngezibuko lokucoca, ezinokucoca intsalela kumatshini, kungekuphela nje ukuqinisekisa umgangatho we-putty, kodwa nokusebenzisa umatshini omnye ngeenjongo ezininzi, kwaye uthenge isixhobo esinye ukuvelisa iintlobo ezahlukeneyo zezixhobo. iputty.
Isizathu sesiHlanu
Umahluko kumgangatho wokuzalisa kwakhona kunokwenzeka ukuba ubangele ukubola. Inani elikhulu lokuzalisa lisetyenziswa ngaphakathi nangaphandle eludongeni putty, kodwa umxholo weCa2CO3 kwipowder enzima ye-calcium kunye ne-talc powder kwiindawo ezahlukeneyo wahlukile, kwaye umahluko kwi-pH uya kubangela ukubola kwe-putty, njengalezo. eChongqing naseChengdu. I-powder yerabha efanayo isetyenziselwa udonga lwangaphakathi lwe-putty powder, kodwa i-talcum powder kunye ne-powder enzima ye-calcium yahlukile. EChongqing, ayiwususi umgubo, kodwa eChengdu, awuwususi umgubo.
isizathu ezintandathu
Isizathu semozulu sisizathu sokukhutshwa komgubo we-putty kwiindonga zangaphakathi nangaphandle. Ngokomzekelo, i-putty kwiindonga zangaphakathi nangaphandle zinemozulu eyomileyo kunye nomoya omhle kwiindawo ezomileyo ezisenyakatho. Kukho imozulu yemvula, umswakama wexesha elide, ipropati yokwenza ifilimu ye-putty ayilungile, kwaye iya kulahlekelwa ngumgubo, ngoko ke ezinye iindawo zifanelekile kwi-putty engenamanzi kunye ne-calcium powder.
isizathu sesixhenxe
Izibophelelo ze-inorganic ezifana nomgubo we-calcium ongwevu kunye nesamente emhlophe azicocekanga kwaye ziqulethe isixa esikhulu sempukane ephindwe kabini. Into ebizwa ngokuba yi-multi-functional grey powder ye-calcium kunye ne-samente emhlophe enemisebenzi emininzi kwimarike ayicocekanga, kuba isixa esikhulu sezi zibophelelo ze-inorganic zisetyenziswa, kwaye i-putty engenamanzi kwiindonga zangaphakathi nangaphandle ngokuqinisekileyo ziya kuba zingenamgubo. kwaye hayi amanzi.
isizathu sesibhozo
Ehlotyeni, ukugcinwa kwamanzi kwi-putty kwiindonga zangaphandle akwanelanga, ngakumbi kwiindawo ezinobushushu obuphezulu kunye ne-ventilation efana neminyango ephezulu kunye neefestile. Ukuba ixesha lokuqala lokumisela i-ash calcium powder kunye ne-samente ayanele, liya kulahlekelwa ngamanzi, kwaye ukuba aligcinwanga kakuhle, liya kuba ngumgubo onzima.
