I-HEMC ye-Putty Powder ixhathisa i-Base Cracking kunye ne-Coating Peeling

I-putty powder isetyenziswa ngokubanzi ekwakhiweni kokugcwalisa kunye nokulungisa iintanda, imingxuma, kunye nokunye ukungafezeki kwiindonga kunye neesilingi. Nangona kunjalo, enye yemiceli mngeni yokusebenza nge-putty kukuqinisekisa ukuba ibambelela kakuhle kumphezulu kwaye ayiqhekezi okanye ayiqhekeki ngokuhamba kwexesha. Oku kubaluleke ngakumbi xa usebenzisa i-putty njengesiseko sokupeyinta okanye ezinye iintlobo zeengubo. Enye indlela yokuphucula ukusebenza kwe-putty kulo mbandela kukongeza i-Hydroxyethyl Methyl Cellulose (HEMC) kumxube. Kweli nqaku, siza kuxubusha iingenelo zokusebenzisa i-HEMC kwi-putty powder ukumelana nokuqhekeka kwesiseko kunye ne-coating peeling, kunye nezinto ekufuneka ziqwalaselwe xa usebenzisa i-HEMC kwesi sicelo.

Iinzuzo zokusebenzisa i-HEMC kwiPutty Powder

Ukuphuculwa kweAdhesion: Enye yeenzuzo eziphambili zokusebenzisa i-HEMC kwi-putty powder kukuphucula ukubambelela. I-HEMC yipolymer enyibilikayo emanzini enokunceda i-putty ibambelele ngokufanelekileyo kumphezulu. Oku kubaluleke ngakumbi xa i-putty isetyenziswe njengesiseko sokupeyinta okanye ezinye iintlobo zeengubo. Ukubambelela okuphuculweyo kunokunceda ukunciphisa amathuba okuqhekeka kwesiseko kunye ne-coating peeling, enokuthi iphucule umgangatho opheleleyo kunye nobomi obude bemveliso egqityiweyo.

Ukunciphisa Ukunciphisa: I-HEMC inokunceda ukunciphisa i-shrinkage kwi-putty. I-Shrinkage ingenzeka xa i-putty yomile kwaye ikhupha kumphezulu, ikhokelela ekuqhekekeni kunye nezinye iintlobo zomonakalo. Ngokunciphisa i-shrinkage, i-HEMC inokunceda ekuqinisekiseni ukuba i-putty ihlala ibambelele ngokuqinileyo kumphezulu, enokukunceda ukunciphisa amathuba okuqhekeka kwesiseko kunye nokuqhawula i-coating.

Ukuphuculwa kokuSebenza: I-HEMC inokuphucula nokusebenza kwe-putty powder. Inokukunceda ukunciphisa i-viscosity yezinto eziphathekayo, okwenza kube lula ukuxuba nokusebenzisa. Oku kunokunceda ukunciphisa umthamo wamanzi afunekayo kumxube, onokuphucula umgangatho opheleleyo kunye nokuqina kwemveliso egqityiweyo.

Ukusebenza kakuhle koKwakha: Ukongeza kwezi zibonelelo zingentla, i-HEMC inokuphucula nokusebenza ngokubanzi kokwakhiwa kwe-putty powder. Oku kubandakanya izinto ezinje ngokuqina koxinzelelo, amandla okuqina, kunye namandla okuguquguquka. Ngokuphucula ezi zakhiwo, i-HEMC inokunceda ekuqinisekiseni ukuba i-putty iyakwazi ukumelana noxinzelelo kunye noxinzelelo lokusetyenziswa okuqhelekileyo, kwaye ihlala ilungile kwisakhiwo ngokuhamba kwexesha.

Izinto ekufuneka ziqwalaselwe xa usebenzisa i-HEMC kwiPutty Powder

Uhlobo lwe-HEMC: Kukho iintlobo ezininzi ze-HEMC ezikhoyo, nganye ineempawu ezahlukeneyo kunye neempawu. Uhlobo lwe-HEMC olulungele i-putty powder luya kuxhomekeka kwizinto ezifana nokuhambelana okufunwayo, i-viscosity, kunye nendlela yesicelo. Ngokuqhelekileyo, i-viscosity ephantsi ukuya ephakathi i-HEMC inconywa kwizicelo ze-putty powder.

Inkqubo yokuxuba: Ukuqinisekisa ukuba i-HEMC ihanjiswa ngokulinganayo kuyo yonke i-putty powder, kubalulekile ukulandela inkqubo efanelekileyo yokuxuba. Oku ngokuqhelekileyo kubandakanya ukongeza i-HEMC emanzini kuqala kwaye udibanise ngokucokisekileyo ngaphambi kokuba ungeze ipowder. Kubalulekile ukuxuba i-putty powder ngokucokisekileyo ukuqinisekisa ukuba i-HEMC ihlakazeke ngokulinganayo kwaye akukho ziqhuma okanye i-clumps.

Isixa se-HEMC: Isixa se-HEMC esiza kongezwa kwi-putty powder siya kuxhomekeka kwiimfuno ezithile zesicelo. Ngokuqhelekileyo, i-concentration ye-0.2% ukuya kwi-0.5% ye-HEMC ngobunzima bepowder iyanconywa ukuba ibambelele ngokufanelekileyo, ukunciphisa ukucutha, ukuphuculwa kokusebenza, kunye nokusebenza kakuhle kokwakhiwa. Nangona kunjalo, inani le-HEMC elifunekayo lingahluka ngokuxhomekeka kuhlobo oluthile lwe-putty powder olusetyenziswayo
