Ingaruka z'ifu ya latex ishobora kongera gushonga ku bwiza bw'ifu ya putty

Ku bijyanye n'ikibazo cy'uko ifu ya putty yoroshye kuyihindura ifu, cyangwa imbaraga zayo zidahagije. Nkuko twese tubizi, ether ya cellulose igomba kongerwamo kugira ngo hakorwe ifu ya putty, HPMC ikoreshwa kuri putty yo ku rukuta, kandi abakoresha benshi ntibashyiramo ifu ya latex ishobora kongera gushonga. Abantu benshi ntibashyiramo ifu ya polymer kugira ngo bazigame ikiguzi, ariko iyi ni nayo mpamvu putty isanzwe yoroshye kuyihindura ifu kandi ikagira ibibazo by'ubuziranenge bw'ibicuruzwa!

Puti isanzwe (nk'iyitwa 821 puti) ikorwa ahanini n'ifu yera, kole nto ya sitashi na CMC (hydroxymethyl cellulose), kandi zimwe zikorwa muri methyl cellulose na Shuangfei powder. Iyi puti ntabwo ifatana kandi ntirinda amazi.

Selulosi ishobora kwinjiza amazi no kubyimba nyuma yo gushonga mu mazi. Ibicuruzwa biva mu nganda zitandukanye bifite igipimo cyo kwinjiza amazi gitandukanye. Selulosi igira uruhare mu kubika amazi muri putty. Putty yumye ifite imbaraga runaka by'igihe gito, kandi irahita ivamo ifu buhoro buhoro nyuma y'igihe kirekire. Ibi bifitanye isano rya hafi n'imiterere ya molekile ya selulosi ubwayo. Putty nk'iyo irarekuye, ifite amazi menshi, yoroshye kuyisya, nta mbaraga ifite, kandi nta bukonje ifite. Iyo topcoat ishyizwe hejuru, PVC nkeya biroroshye guturika no gushonga; PVC nini yoroshye kuyigabanya no kuyica; bitewe n'uko amazi menshi anyurwamo, izagira ingaruka ku miterere ya filime no ku ngaruka z'ubwubatsi bwa topcoat.

Niba ushaka kunoza ibibazo byavuzwe haruguru bya putty, ushobora guhindura formula ya putty, wongeramo ifu ya latex ishobora kongera gushonga neza kugira ngo wongere imbaraga za putty, hanyuma ugahitamo hydroxypropyl methylcellulose HPMC nziza kandi ifite ubuziranenge bwizewe.

Mu gihe cyo gukora putty, niba ingano y'ifu ya latex ishobora kongera gushonga yongewemo idahagije, cyangwa niba hakoreshejwe ifu ya latex idahagije kuri putty, ni izihe ngaruka bizagira ku ifu ya putty?

Ifu ya latex ishobora kongera gushonga idahagije, ikigaragara cyane ni uko urwego rwa putty rurekuye, ubuso bwarasenyutse, irangi rikoreshwa mu gusiga hejuru ni rinini, ubushobozi bwo kuringaniza ni bubi, ubuso buba bubi nyuma yo gukora firime, kandi biragoye gukora firime y'irangi ryinshi. Inkuta nk'izo zikunze gushibuka, gushwanyagurika, gushwanyagurika no kwangirika kwa firime y'irangi. Iyo uhisemo ifu ya putty idahagije, biragaragara ko imyuka mibi nka formaldehyde ikorerwa ku rukuta yangiza umubiri w'abandi.
