Styrene Qib Kev Lag Luam: Cov Khoom Xyaw Tseem Ceeb Rau Kev Tsim Cov Roj Hmab

piav qhia luv luv:

Cov mis molecular: C₈H₈

Styrene yog ib yam khoom tseem ceeb hauv petrochemical thiab yog ib hom polymer monomer uas siv tau ntau yam hauv kev lag luam thoob ntiaj teb. Cov kua roj no tsis muaj xim, pob tshab thiab muaj ntxhiab tsw qab, nws tsis yaj hauv dej tab sis nws sib xyaw nrog feem ntau cov kuab tshuaj organic, ua rau styrene yog ib yam khoom siv tseem ceeb rau kev tsim cov yas. Ua ib qho khoom siv nruab nrab, styrene feem ntau yog siv los tsim polystyrene, ABS resin, thiab roj hmab hluavtaws, uas ua rau muaj kev hloov pauv tshiab hauv kev ntim khoom, kev tsim kho, thiab kev lag luam tsheb. Qhov tseem ceeb, styrene yooj yim polymerization ntawm chav tsev kub, yog li cov tshuaj inhibitors xws li hydroquinone yog qhov tseem ceeb rau kev khaws cia thiab kev thauj mus los kom muaj kev nyab xeeb. Nrog nws cov khoom siv tshuaj ruaj khov thiab kev siv dav, styrene tseem yog lub hauv paus ntawm kev tsim cov polymer niaj hnub no, txhawb nqa ntau yam kev lag luam thoob ntiaj teb.

Styrene (CAS 100-42-5)yog ib qho tseem ceeb ntawm cov roj av petrochemical monomer thiab lub hauv paus tseem ceeb rau kev tsim cov polymer niaj hnub no, uas tau ua kev zoo siab rau nws txoj kev ua haujlwm polymerization zoo heev thiab kev sib raug zoo ntawm cov khoom siv. Ua ib qho khoom siv ntau yam, nws ua haujlwm ua cov khoom xyaw tseem ceeb rau kev tsim cov polymers ua tau zoo, ua rau muaj kev tsim cov khoom siv ruaj khov, ua tau raws li cov kev cai nruj ntawm kev lag luam.

Siv dav thoob plaws ntiaj teb, nws feem ntau yog siv los tsim cov polystyrene (PS), ABS resin, styrene-butadiene roj hmab (SBR), thiab unsaturated polyester resins (UPR), uas txhawb nqa ntxiv rau kev lag luam xws li kev ntim khoom, cov khoom siv sab hauv tsheb, kev rwb thaiv tsev, cov khoom siv hluav taws xob, thiab cov khoom siv kho mob.

Peb cov khoom styrene muaj ntau qib xaiv (kev lag luam, polymerization, thiab high-purity) kom haum rau ntau yam kev xav tau ntawm kev tsim khoom, nrog rau kev tswj xyuas zoo kom ntseeg tau tias muaj cov khoom tsis huv tsawg thiab cov monomer reactivity ruaj khov. Peb lav qhov kev xa khoom ntau, cov ntaub ntawv pov thawj khoom phom sij tiav (xws li MSDS, daim ntawv pov thawj UN), thiab cov kev daws teeb meem logistics rau kev thauj mus los ntawm cov kua dej uas yooj yim hlawv. Tsis tas li ntawd, peb pab neeg tshaj lij muab kev txhawb nqa tus kheej - xws li kev xaiv cov tshuaj inhibitor thiab kev qhia khaws cia - kom ua kom koj cov khoom tsim tau zoo thiab muaj kev nyab xeeb.
