Polyisobutylene (PIB)yog ib qho tsis muaj kob, cov tsis tau, cov tshuaj tiv thaiv kab mob, huab cua tsis kam, acid thiab alkali ua hauj lwm zoo ua tau zoo. Polyisobutylene yog ib qho tsis muaj kob, tsis muaj ntxhiab, tsis muaj tshuaj lom isobutylene homopolymer hompolymer homopolymer homopolymer homopolymer homopolymer homopolymer homopolymer homopolymer homoploylene homoprolymer. Vim tias qhov kev npaj sib txawv thiab thev naus laus zis molecological, cov nyiaj molecological ntawm polyisobutylene sib txawv hauv ntau yam. Feem ntau ntawm cov khoom hnyav ntawm cov khoom lag luam ncav cuag ntau tshaj 10,000 txog 200,000 yuav hloov dua tshiab los ntawm cov kua tuab rau ib nrab, thiab tom qab ntawd hloov mus rau roj hmab zoo li Elastomer. Polyisobutylene yog resistant rau acid, alkali, dej, ozone thiab laus, thiab muaj cov pa hluav taws xob zoo thiab muaj hluav taws xob.
Tshuaj lom neeg cov khoom:Tsis muaj xim rau lub teeb daj viscous kua lossis elasticle semisolid (qis molecular hnyav yog mos gelatinous hnyav, siab molecular hnyav yog ducasty thiab elastic). Txhua tus ntxhiab tsw ntxhiab, tsis muaj ntxhiab lossis tsw ntxhiab tsw ntxhiab tsw ntxhiab. Qhov nruab nrab molecular hnyav yog 200,000 ~ 87 lab. Soluble nyob rau hauv Benzene thiab Diisobuty Iptib phau ntawv, tuaj yeem ua kom tiav nrog polyvinyl acetate, siv quav ciab, insoluble hauv dej, cawv thiab lwm yam kuab tshuaj polar. Nws tuaj yeem ua cov pos hniav thaj muaj cov muag muag zoo heev ntawm qhov kub thiab txias zoo heev, thiab huab cua sov, kub heev thaum nws ntsib qhov ncauj kub.
Cov Ntawv Thov:PIB paub txog nws cov khoom sib khi zoo thiab cov khoom nplaum zoo nkauj, uas feem ntau siv hauv cov nplaum, thiab cov tshuaj pleev plhu. Piv siv roj hmab-zoo li cov khoom siv ua nws qhov kev xaiv zoo rau kev sib khi thiab daim ntawv thov sib khi, raws li nws pab muab cov nyiaj ua kom muaj zog thiab ruaj khov. Ntxiv nrog rau nws cov kev siv tswv yim, PIB feem ntau siv hauv cov tshuaj pleev ib ce thiab cov kev saib xyuas tus kheej vim nws cov khoom siv solubility zoo heev. Cov tshuaj feem ntau yog sib xyaw ua ke nrog lwm cov khoom xyaw los tsim cov khoom lag luam nrog lub meej mom tshwj xeeb thiab hnov.
Pib muaj ntau cov kev siv hauv kev lag luam khoom noj khoom haus ib yam nkaus. Cov tshuaj yog ib txwm siv los ua cov tuab dua, stabilizer, thiab emulsifier hauv cov zaub mov tiav. PIB tseem tuaj yeem pab txhim kho cov qauv thiab cov khoom lag luam xws li xws li cov mis nyuj khov, zom zom cov pos hniav, thiab cov khoom ci. Cov versatility ntawm pib ua rau nws muaj cov khoom siv tseem ceeb rau cov tuam ntxhab hauv kev lag luam khoom noj.
PIB tseem dav siv hauv kev kho mob. Cov tshuaj uas tsis yog-lom cov khoom ua rau nws zoo tagnrho rau kev siv hauv kev siv khomob. Cov tshuaj feem ntau siv los ua cov khoom siv khov kho hauv cov tshuaj tiv thaiv, nrog rau cov khoom siv hauv ntau cov tshuaj. Piv txwv li cov kab hydrophobic pab nws ua raws li ntawm daim tawv nqaij, ua rau nws muaj txiaj ntsig hauv kev tsim cov khoom noj kho mob.
Cov yam ntxwv:Polyisobutylene muaj cov tshuaj lom neeg ntawm cov pa roj khov kho, thiab cov pab pawg sib txuas ua ke faib, uas yog ib lub cim polymer. Cov kev sib sau ua ke xeev thiab cov khoom ntawm polyisobutylene nyob ntawm nws cov leeg hnyav thiab cov khoom hnyav molecular. Thaum lub viscosity nruab nrab molecular hnyav yog nyob rau hauv ntau yam ntawm 70000 ~ 90000, polyisobutylene hloov los ntawm cov kua tig mus rau ib qho khoom siv ywj. Feem ntau, raws li qhov loj me ntawm cov molecular ceeb thawj ntawm polyisobutylene tau muab faib ua cov koob hauv qab no: Tsawg molecular hnyav polyisobutylene (naj npawb nruab nrab molecular hnyav = 200-10000); Nruab nrab molecular phaus polyisobutylene (tus lej nruab nrab molecular hnyav = 20000-45,000); High molecular hnyav polyisobutylene (naj npawb nruab nrab molecular hnyav = 75,000-700,000); Ultra High Molecular Nyhav Polyisobutylene (tus naj npawb ntawm nruab nrab molecular hnyav hnyav tshaj li 760000).
1. Cua nruj
Ib qho ntawm cov yam ntxwv uas zoo tshaj plaws ntawm Polyisobutylene yog nws cov huab cua zoo heev. Vim tias muaj ob pawg metryl, cov molecular chains txav yog qeeb thiab ntim dawb yog me me. Qhov no ua rau muaj kev sib txawv qis coeffusic thiab roj permeability.
2. Solubility
Polyisobutylene yog soluble hauv aliphatic hydrocarbon, roj av hydrocarbon, roj av, cov ntxhia roj, canbon monosulfide. Ib feem uas yaj hauv cov cawv ntau dua thiab cov roj ntsha, cov roj thiab cov roj thiab cov roj hmab thiab cov roj hmab thiab cov roj hmab thiab cov roj muaj roj ntau ntxiv; Insoluble nyob rau hauv cov dej cawv (xws li Methanol, Erthylene glycol), ketones (xws li acetone, metylenchen ketone) thiab glacial acetic acid.
3. Tshuaj lom neeg
Polyisobutylene yog resistant rau kua qaub thiab alkali. Xws li ammooroChia, hydrochloric acid, 60% hydrofluoric acid, 405% phosphoric acid, 300} nitric acid yaig + txawm li cas los xij, nws tsis tuaj yeem tiv thaiv cov yaig ntawm cov muaj zog oxidants, kub tsis muaj zog oxidants (xws li 60% poov tshuaj Tso cai), qee cov kua qaub kub organic (xws li 373k acetic acid) thiab halogens (fluorine, suab puam).
