Yintoni into ekrwada ye-putty eludongeni?

I-Wall putty yinto yokwakha eyaziwayo esetyenziswa kuzo zombini izakhiwo zokuhlala kunye nezorhwebo. Yimpahla eguquguqukayo esetyenziselwa ukugudisa kunye nokugqiba iindonga zangaphakathi kunye nezangaphandle ngaphambi kokupeyinta okanye ukwenza iphepha lodonga. I-Wall putty yenziwe ngezinto ezahlukeneyo ekrwada ezixutywe kunye ukwenza into engqindilili efana nentlama. Kule nqaku, siza kuxubusha ngokubanzi izinto eziluhlaza ze-putty eludongeni.

Isamente emhlophe:
I-samente emhlophe yinto yokuqala esetyenziswa kwi-putty eludongeni. Sisibophelelo esisebenza ngehydraulic esenziwe ngeklinka emhlophe egayiweyo ecolekileyo kunye negypsum. I-samente emhlophe inezinga eliphezulu lobumhlophe kunye nomxholo ophantsi wentsimbi kunye ne-manganese oxide. Ikhethwa kwi-putty eludongeni njengoko ibonelela ngokugqitywa kakuhle kwiindonga, ineempawu ezintle zokubambelela, kwaye iyamelana namanzi.

Umgubo wemarble:
Umgubo wemarble yimveliso yokusikwa kunye nokupholisha. Igudiswe kakuhle kwaye isetyenziswe kwi-putty eludongeni ukuqinisa amandla kunye nokuqina kwayo. I-marble powder yiminerali yendalo etyebileyo kwi-calcium kwaye ineempawu ezintle zokudibanisa. Inceda ekunciphiseni i-shrinkage ye-putty kwaye inika ukugqiba kakuhle kwiindonga.

Umgubo weTalcum:
I-Talcum powder iyiminerali ethambileyo esetyenziswa kwi-putty eludongeni ukuphucula ukusebenza kwayo kunye nokunciphisa i-viscosity yomxube. Icolekile kwaye inobunyulu obuphezulu. I-Talcum powder inceda ekusebenziseni okulula kwe-putty kwaye iphucula ukunamathela kwayo kwiindonga.

Udongwe lwaseTshayina:
Udongwe lwase China, olukwabizwa ngokuba yi kaolin, yiminerali yendalo esetyenziswa kwi putty eludongeni njengesigcwalisi. Icolekile kwaye inobumhlophe obuphezulu. Udongwe lwaseTshayina yinto engabizi kakhulu esetyenziselwa ukuphucula ubuninzi be-putty kunye nokunciphisa iindleko zayo.

Mica powder:
I-Mica powder yiminerali yendalo esetyenziswa kwi-putty eludongeni ukubonelela ngokugqitywa kwe-glossy kwiindonga. Icolekile kwaye inomgangatho ophezulu wokuzibonakalisa. I-Mica powder inceda ekunciphiseni i-porosity ye-putty kwaye inikezela ukuchasana kakuhle kwamanzi.

Isanti yesilika:
Isanti ye-silica yiminerali yendalo esetyenziswa kwi-putty eludongeni njengento yokuzalisa. Icolekile kwaye inobunyulu obuphezulu. Isanti ye-silica inceda ekuphuculeni amandla e-putty kwaye iyanciphisa ukucutheka kwayo. Kwakhona kunceda ekuphuculeni ukunamathela kwe-putty kwiindonga.

Amanzi:
Amanzi ayinxalenye ebalulekileyo ye-putty eludongeni. Isetyenziselwa ukuxuba imathiriyeli ekrwada kunye kwaye yenze into efana nentlama. Amanzi anceda ekusebenzeni iipropati ezibophezelayo ze-samente kwaye zibonelela nge-fluidity efunekayo kumxube.

Izongezo zekhemikhali:
Izongezo zekhemikhali zisetyenziselwa kwi-putty eludongeni ukuphucula iimpawu zayo kunye nokusebenza. Ezi zongezelelo ziquka iiretarders, iiaccelerators, iiplasticizers, nezinto ezikhusela amanzi. I-retarders isetyenziselwa ukucotha ixesha lokumisela i-putty, ngelixa i-accelerators isetyenziselwa ukukhawulezisa ixesha lokumisela. Iiplastiki zisetyenziselwa ukuphucula ukusebenza kunye nokunciphisa i-viscosity ye-putty, ngelixa ii-agent zokukhusela amanzi zisetyenziselwa ukwenza i-putty inganyangeki.

I-Methyl celluloseluhlobo oluqhelekileyo lwe-cellulose ether esetyenziswa kwi putty eludongeni. Yenziwe ngokuguqulwa kweekhemikhali zeselulosi yendalo usebenzisa i-methanol kunye ne-alkali. I-Methyl cellulose ngumgubo omhlophe, ongenavumba, kwaye ongenancasa onyibilikayo emanzini kwaye wenze isisombululo esicacileyo kunye ne-viscous. Ineempawu ezilungileyo zokugcina amanzi kwaye iphucula ukusebenza kwe-putty. I-Methyl cellulose ikwabonelela ngokubambelela kakuhle kwii-substrates ezahlukeneyo kwaye iphucula amandla okuqina kweputty.

I-Hydroxyethyl cellulose lolunye uhlobo lwe-ether ye-cellulose esetyenziswa kwi-putty eludongeni. Yenziwe ngokuguqulwa kweekhemikhali ze-cellulose yendalo usebenzisa i-ethylene oxide kunye ne-alkali. I-Hydroxyethyl cellulose ngumgubo omhlophe, ongenavumba, kwaye ongenancasa onyibilikayo emanzini kwaye wenze isisombululo esicacileyo kunye ne-viscous. Ineempawu ezilungileyo zokugcina amanzi kwaye iphucula ukusebenza kwe-putty. Iselulosi yeHydroxyethyl ikwabonelela ngokuncamathela kakuhle kwiisubstrates ezahlukeneyo kwaye iphucula ukomelela kweputty.

I-Carboxymethyl cellulose ikwasetyenziswa kwi-putty eludongeni njenge-thickener kunye ne-binder. Yenziwe ngokuguqulwa kweekhemikhali zeselulosi yendalo usebenzisa i-monochloroacetic acid kunye ne-alkali. I-Carboxymethyl cellulose ngumgubo omhlophe, ongenavumba, kwaye ongenancasa onyibilikayo emanzini kwaye wenze isisombululo esicacileyo kunye ne-viscous. Ineempawu ezilungileyo zokugcina amanzi kwaye iphucula ukusebenza kwe-putty. I-Carboxymethyl cellulose ikwabonelela ngokubambelela kakuhle kwii-substrates ezahlukeneyo kwaye iphucula ukomelela kwe-putty.

 

Ukuqukumbela, i-wall putty yenziwe ngezinto ezahlukeneyo ezixutywe kunye ukwenza into efana ne-paste. Eyona nto isetyenziswa eludongeni i-putty yisamente emhlophe, ngelixa ezinye izinto ezisetyenziswayo ziquka umgubo wemarble, i-talcum powder, udongwe lwe-china, i-mica powder, isanti ye-silica, amanzi, kunye nezongezo zemichiza. Ezi zixhobo eziluhlaza zikhethwa kwiimpawu zazo ezithile, ezinjengobumhlophe, iipropati ezibophezelayo, ukusebenza, kunye nokuqina, ukubonelela ngokugqitywa okugudileyo kunye nokukhanya kweendonga.
