HIPS yog cov lus Askiv luv rau cov tshuaj polystyrene uas tiv taus kev cuam tshuam, cov khoom siv tseem ceeb yog styrene, nrog rau kev ua kom muaj zog, kev cuam tshuam siab, kev ruaj khov ntawm qhov ntev, yooj yim rau cov duab thiab cov txheej txheem thiab ntau lwm yam ntxwv, tuaj yeem siv dav hauv cov khoom siv hauv tsev, cov twj paj nruag thiab cov khoom siv, cov khoom ua si,ntim khoom pov tseg, kev tsim kho teb. Qhov kev tiv thaiv ntawm styrene tsis zoo, thiab nws cov khoom yog brittle thiab yooj yim tawg los ntawm kev sib tsoo. Ntxiv styrene butadiene roj hmab me me rau styrene tuaj yeem txhim kho nws qhov kev tiv thaiv kev cuam tshuam, thiab cov roj hmab butadiene feem ntau siv yog butadiene, uas muaj kev tiv thaiv kev cuam tshuam zoo heev.

Tam sim no muaj ob txoj kev los npaj cov polystyrene uas tiv taus kev cuam tshuam, uas yog txoj kev sib xyaw thiab txoj kev sib txuas ua ke. Txoj kev sib xyaw, ua ntej tshaj plaws, butadiene thiab styrene sib xyaw ua ke raws li qhov sib xyaw, tom qab ntawd cov khoom sib xyaw rau hauv lub tshuab extruder sib xyaw kom sib npaug, extruded zaj duab xis nyias txias, thiab thaum kawg txiav rau hauvHIPScov hlais nrog rab txiab, cov txheej txheem yuav tsum tau them sai sai rau qhov sib tov sib xyaw kom sib npaug.

Hauv txoj kev graft copolymerisation, butadiene cov khoom me me raug yaj hauv styrene monomer, thiab cov tshuaj copolymerisation tshwm sim nrog kev pab los ntawm catalyst peroxide, thiab cov khoom copolymerisation thaum kawg muab tso rau hauv extruder rau granulation. Hauv kev xyaum, HIP yas feem ntau thiab ABS resin rau cov ntaub ntawv sib txuas, HIPS khoom pheej yig dua ABS resin, tab sis cov khoom siv kho tshuab qis dua ABS resin, kev lag luam kev tsim kho yuav raws li tus nqi ntawm ob qho tib si kev ua lag luam rau kev yuav khoom, yog li HIPS yas nqi hloov pauv nrog tus nqi ntawmABSYog tias tus nqi ABS siab, nws yuav tsav HIPS kev lag luam xav tau, ntawm chav kawm, qhov cuam tshuam ntawm HIPS Yas nqi yog qhov tseem ceeb tshaj plaws yog cov khoom siv styrene, tam sim no cov khoom siv styrene tseem ruaj khov, qhov kev thov downstream yog dav dav, tus nqi ruaj khov tiav. Nyob rau hauv lub sijhawm ntev, xyoo no polypropylene lub peev xwm tsim khoom tsawg, thiab xyoo tom ntej cov khoom siv tsim khoom yuav tsum tau ncua, qhov kev pom tag nrho, kev muab khoom tseem tsis txaus, tab sis ob xyoos dhau los qhov kev thov downstream qeeb qeeb, qhov kev pom tag nrho, kev lag luam yuav tsum tau txav mus rau saum, tab sis ruaj khov dua. Qhov no qhia tau hais tias sab nqi tsis muaj kev tsav tsheb zoo. Hauv ob xyoos dhau los, Tuam Tshoj cov khoom siv hauv tsev xav tau kev lag luam pib qeeb qeeb, tab sis raws li cov ntaub ntawv loj, kev txawj ntse artificial, kev lag luam pem hauv ntej yuav coj mus rau hauv nthwv dej ntawm lub caij nthwv dej, uas yuav ua rau kev lag luam raw khoom xav tau, luv luv qhov kev thov sab nyuaj rau muaj kev txhim kho loj, yog li sab kev thov yog qhov tsis zoo.
