Cov khoom

Cov khoom no yog siv los ua cov roj nplua nyeem thiab cov pwm tso tawm rau kev ua cov yas xws li polyvinyl chloride, polystyrene, thiab urea-formaldehyde resin.Nws muaj zoo heev sab nraud lubrication thiab pwm tso tawm zog.Nws kuj muaj qhov zoo pob tshab thiab hluav taws xob rwb thaiv tsev.Thaum siv rau cov pob tshab extrusion molding, qhov ntau npaum li cas yog 0.3 txog 0.8 feem.Txawm li cas los xij, lubricity ntawm cov khoom no tsis zoo li stearic acid.Cov nyhuv kav ntev yog luv luv, thermal stability tsis zoo, thiab nws muaj xim pib.Kev sib xyaw nrog me me ntawm cov cawv ntau dua tuaj yeem kov yeej cov kev tsis txaus siab saum toj no.Yog hais tias tus nqi ntawm cov resin loj heev, nws yooj yim los nag rau saum npoo ntawm cov khoom, uas cuam tshuam rau kev luam tawm thiab pob tshab.Cov khoom no tseem tuaj yeem siv los ua tus neeg sawv cev rau cov khoom siv polyolefins thiab cov khoom siv los tiv thaiv cov yeeb yaj kiab.Nws tseem tuaj yeem siv los ua cov pwm tso tawm sab hauv thiab cov roj nplaum rau cov roj hmab ntuj thiab cov roj hmab hluavtaws los txhim kho cov txheej txheem ntawm cov roj hmab.Txhim kho cov nyhuv dispersion ntawm lwm yam additives xws li pigments, thiab muab cov khoom zoo gloss.Rau cov roj-raws li drilling kua emulsifier, hlau hlau kos duab lubricant.
