I-Putty powder iyimpahla yokwakha ethandwayo esetshenziselwa ukuhlanganisa nokulungisa kabusha izindonga, uphahla kanye nezinye izindawo. Kuyingxube yezinto ezihlukahlukene ezifana usimende, ukugcwalisa kanye ne-binder. I-Hydroxypropylmethylcellulose (HPMC) ingenye yezibophezelo ezisetshenziswa ku-putty powder. I-HPMC iyi-polymer engeyona enobuthi, engenaphunga ethuthukisa ukusebenza kwezimpushana ze-putty. Isetshenziswa ekuqhekekeni kwezinhlobo ezahlukahlukene ze-putty ukuthuthukisa ukusebenza kwayo. Lesi sihloko sizoxoxa ngezinhlobo ezine zokuqhekeka kwe-putty kanye nendlela yokusebenzisa i-HPMC kuhlobo ngalunye.
Izinhlobo ezine ze-putty cracks zimi kanje:
1. Imifantu yokuncipha
Ukuqhekeka kwe-shrinkage ngenxa ye-putty eyomile. Njengoba i-putty yoma, iyashwabana, ibangele ukuba kuvele imifantu ebusweni. Ubunzima bale mifantu buncike ekubunjweni kwe-putty. I-HPMC ingangezwa ku-putty ukunciphisa imifantu yokuncipha. I-HPMC isebenza njenge-ejenti egcina amanzi, inciphisa inqubo yokomisa futhi ivumele i-putty ukuthi yome ngokulinganayo. Ibuye inciphise inani lamanzi adingekayo ukuze kuhlanganiswe i-putty, okusiza ukunciphisa ukuncipha ngesikhathi somisa.
2. Umfantu oshisayo
Ukuqhekeka okushisayo kubangelwa ukwanda nokufinyela kwempahla njengoba izinga lokushisa lishintsha. Zivamile emabhilidini anokushintshashintsha kwezinga lokushisa okukhulu, njengasezindaweni ezinesimo sezulu esibi kakhulu. I-HPMC ingasiza ekunciphiseni ukuqhekeka okushisayo ngokwandisa izindawo zokugcina amanzi zama-putty. I-polymer isebenza njenge-binder esiza ukubamba ezinye izingxenye ze-putty ndawonye. Lokhu kunciphisa ingozi yokuqhekeka ngenxa yokwanda nokuncipha kwezinga lokushisa.
3. Ukuqinisa imifantu
Ukuqina kwemifantu kubangelwa ukuqina kwe-putty. Njengoba i-putty iqina, ilahlekelwa okunye ukuguquguquka kwayo, okubangela ukuthi iqhekeke. I-HPMC ingasiza ekunciphiseni imifantu eqina ngokwandisa ukuguquguquka kwe-putty. Le polymer isebenza njenge-plasticizer, okwenza i-putty iguquguquke. Lokhu kuyivumela ukuthi imelane nokunyakaza kwendawo ependwe kuyo, kunciphise ingozi yokuqhekeka.
4. Imifantu yesakhiwo
Ukuqhekeka kwesakhiwo kwenzeka ngenxa yokunyakaza kwesakhiwo noma indawo engaphansi. Zingabangelwa izici ezihlukahlukene, njengokuncipha, ukuzamazama komhlaba, noma ukushintsha komswakama ongaphezulu. I-HPMC ingasiza ekunciphiseni ukuqhekeka kwesakhiwo ngokuthuthukisa izakhiwo zokunamathela zama-putty. I-polymer isebenza njenge-binder, isiza i-putty ukuthi inamathele ngokuphumelelayo phezulu. Lokhu kunciphisa ingozi yokuqhekeka ngenxa yokunyakaza kwendawo engaphansi.
I-HPMC iyisithako esibalulekile kuma-putty powders ngoba ingasiza ekuthuthukiseni ukusebenza kwezinhlobo ezihlukahlukene zokuqhekeka kwe-putty. Ngokunciphisa ubungozi bokushwabana, ukushisa, ukuqina nokuqhekeka kwesakhiwo, i-HPMC ingasiza ekuqinisekiseni ukuthi ama-putty ahlala isikhathi eside futhi agcine ubuhle bawo. Njengoba imboni yezokwakha iqhubeka nokuvela, i-HPMC isalokhu iyisithako esibalulekile kuma-putty kuzo zonke izicelo zokwakha.
