Lub hauv paus ntsiab lus ntawm kev siv cov hnab looj tes pov tseg yog feem ntau ntawm cov yeeb yaj kiab - tsim thiab thaiv cov khoom ntawm cov ntaub ntawv polymer; kev ua haujlwm tsim cov yeeb yaj kiab tsis tu ncua, tiv thaiv tsis tu ncua uas cais cov tes ntawm ib puag ncig sab nraud. Thaum lub sijhawm tsim khoom, cov khoom siv yas lossis roj hmab tau dhau los ua cov txheej txheem xws li kev sib xyaw, cua sov, thiab molding kom ntseeg tau tias muaj kev tiv thaiv zoo ib yam ntawm tes- cov pwm pwm, thaum kawg tsim cov hnab looj tes nrog cov tuab thiab lub zog.
Kev tiv thaiv kev ua haujlwm ntawm cov hnab looj tes pov tseg feem ntau yog nyob ntawm cov khoom thaiv ntawm cov ntaub ntawv lawv tus kheej. Cov khoom siv hnab looj tes txo qis kev sib cuag ncaj qha ntawm daim tawv nqaij thiab cov kua dej, stains, kab mob, thiab qee yam tshuaj, yog li txo qhov kev pheej hmoo ntawm kev kis kab mob thiab khaus khaus. Cov ntaub ntawv sib txawv muaj cov yam ntxwv ua tau zoo; Piv txwv li, PE hnab looj tes cia siab rau cov yeeb yaj kiab yas rau kev sib cais yooj yim, thaum cov hnab looj tes nitrile thiab latex siv cov elasticity thiab ntom qauv ntawm cov roj hmab los txhim kho kev haum thiab kev tiv thaiv.
Cov hnab looj tes pov tseg feem ntau yog tsim los ntawm kev siv dip- txheej txheem molding. Tom qab ntxuav thiab ziab, tes pwm yog immersed nyob rau hauv cov kua raw cov ntaub ntawv, cia cov khoom ua raws li tusyees rau pwm nto; tom qab cua sov-vulcanization los yog kho- ua rau cov hnab looj tes ruaj khov. Thaum kawg, cov kauj ruam xws li stripping, tshuaj xyuas, thiab ntim khoom ua rau cov hnab looj tes pov tseg uas ua tau raws li qhov yuav tsum tau siv.
Kev ua tau zoo ntawm cov hnab looj tes pov tseg kuj tseem suav nrog kev hloov kho cov khoom siv thiab kev txhim kho cov txheej txheem ntau lawm. Piv txwv li, kho cov formulation tuaj yeem txhim kho elasticity, abrasion tsis kam, thiab lub zog tsim kua muag, thaum tswj cov tuab thiab cov txheej txheem kho saum npoo tuaj yeem txhim kho hnav kev nplij siab thiab kev ua haujlwm zoo. Nrog rau kev txhim kho thev naus laus zis, cov hnab looj tes pov tseg tau nce zuj zus mus ua nyias thiab sib dua, siab dua - ua tau zoo, thiab zoo ib puag ncig.
