Vim li cas cov tshuaj yas thoob yas tsis yooj yim kom tawg

Cov ntaub ntawv siv feem ntau tshuab nrog cov plastics xws li polyethylene thiab polyester, thiab siv rau glacial acetic acid, t-butanol peroxide, cov roj av phom sij cov khoom lag luam, thiab acid-base corrosive tshuaj. Cov thawv roj hmab yog pawg thiab khaws cia rau hauv chaw ntim, qhov hnyav, thiab cov kaus poom. Tag nrho cov txheej txheem zoo heev txuag tau chaw thiab txuag cov khoom. Lub teeb yuag, tiv taus txias, tiv taus corrosion, paug qias neeg, super huv, nyob rau hauv txoj kab nrog kev kuaj mob. Tshuaj lom neeg cov kab yas tsis yooj yim rau tawg yog tias lawv muaj cov yam ntxwv li nram no: Nws yog cov siab sib xyaw ua ke organic organic, uas tuaj yeem muaj nyob hauv ntau hom xws li kua roj colloidal tov, thiab lwm yam Nws tuaj yeem tsim ua ntau yam ntawm cov plastics vim muaj ntau hom kev sib txawv ntawm monomer. Cov khoom lag luam dav dav muaj ntau yam. Cov txheej txheem sib txawv tuaj yeem siv nrog cov khoom sib txawv. Kev siv tshuaj tua kab yas hauv tshuab yas yuav muab faib ua ob hom thermosetting thiab thermoplasticity. Tus qub tsis tuaj yeem rov kho dua thiab siv tau, thiab tom kawg tuaj yeem tsim dua. Yeej muaj ob hom qauv yas polymer: qhov ib yog qauv txheej, polymer compound muaj cov qauv zoo li no hu ua linear polymer compound, thiab qhov thib ob yog cov qauv txheej txheem, thiab polymer compound muaj cov qauv zoo li no. hu ua bulk polymer compound. Qee cov polymers muaj ib txoj xov hu ua branched polymer, uas yog cov qauv linear. Qee cov polymers muaj qhov sib txuas ntawm cov molecules, tab sis cov ntoo khaub lig-sib txuas yog tsawg dua. Nws yog hu ua cov qauv network thiab belongs rau lub cev qauv.https://www.fhpails.com/
