I-Polyisobutylene CAS 9003-27-4
I-Polyisobutylene (PIB, CAS 9003-27-4) yi-polymer eyomeleleyo efunyenwe yi-cationic polymerization ye-isobutylene monomer. Ayinatyhefu, ayinavumba, izinzile kakhulu, ayingeni moya kakhulu, ikhusela kakhulu, kwaye imo yayo iyatshintsha ukusuka kwi-viscous liquid → semi-solid → rubber elastomer njengoko ubunzima be-molecular bukhula.
Imelana kakhulu nokwaluphala kunye nokuzinza kweekhemikhali
Ukwanda kwe-chain epheleleyo: iyamelana nobushushu, ioksijini, i-ozone, imisebe ye-ultraviolet, ii-asidi, ii-alkali kunye neetyuwa, ayiboli okanye ibe buthathaka ixesha elide
Uzinzo lobushushu: lungasetyenziswa ixesha elide kwi -50℃ ukuya kwi 150℃, lune flash point ephezulu kwaye lunokutsha okuphantsi
Umoya ophezulu + ubushushu obuphezulu + ukungena kwamanzi okuphantsi
Umoya onamandla kakhulu: iipropati ezibalaseleyo zokuthintela amanzi, igesi kunye nomphunga, zingcono kakhulu kunerabha eqhelekileyo
Ubushushu obuhle bombane: ukumelana nomthamo ophezulu, ilahleko ephantsi ye-dielectric, ifanelekile kwiintambo/ukuvalwa kombane
Ukuhambelana okukhuselekileyo nokungeyotyhefu + okubanzi
I-FDA yokutya okusemgangathweni: ayisiyotyhefu, ayicaphukisi, ingasetyenziswa kwitshungama yokutshiza, kwizinto zokuthambisa, kwizinto ezinceda amayeza
Ingaxutywa neehydrocarbons/irabha/iresin: kulula ukuyixuba nokuyitshintsha, iphucula ukuxinana, ukuguquguquka kunye nokumelana nemozulu.

I-PIB yobunzima obuphantsi be-molecular (Mw < 10,000, ulwelo oluqinileyo)
Izinto zokuthambisa/izongezo zepetroli: ukuqina, ukuthintela ukujiya, ukuthintela ukuguguleka, ukuvala kunye nokuthintela ukuvuza
Izinto zokuncamathelisa/zokutywina: iglu ebuthathaka kuxinzelelo, irabha ye-butyl eguquliweyo, iglu engangeni manzi, iglu yokutywina iifestile zemoto
Izinto zokuthambisa / iimveliso zobuhle: i-lipstick / i-lip balm (efumisa ngaphandle kokuthambisa), i-cream (evala umswakama kwaye yenze ifilimu), endaweni ye-squalane
Ukutya: isiseko setshungama yokuhlafuna (ukuphucula ukuhlafuna, ukuthintela ukunamathela kwamazinyo)
2) Ubunzima obuphakathi be-molecular PIB (Mw 10,000 - 100,000, irabha eqinileyo/ethambileyo)
Ukuguqulwa kwerabha: i-acrylonitrile / i-chloroprene rubber plasticizer, ephucula ukumelana neoyile kunye nokuxinana komoya
Iintambo/iintambo: ukufakelwa kwe-insulation, i-sheath engangeni manzi, ukufakelwa kwe-coating engangenisi manzi
Iingubo / i-asphalt: i-anti-corrosion coating, i-asphalt modification (anti-cracking, anti-agles)
3) Ubunzima obuphezulu be-molecular PIB (Mw > 100,000, i-elastomer efana nerabha)
Irabha ekhethekileyo: itayara yangaphakathi engenamoya omninzi, icandelo lokutywina nge-vacuum, i-gasket yokulwa nokwaluphala
Ukuguqulwa kweplastiki: Ukuqinisa i-PP/PE, ukuphucula ukumelana nempembelelo kunye nokumelana nemozulu
• Ukupakisha okuqhelekileyo: 25 kg/ibhegi; 25 kg/idrama
• I-MOQ: kufuneka iqinisekiswe ngokwebanga nendawo ekuyiwa kuyo
• Ixesha lokuKhokhela: liza kuqinisekiswa ngobungakanani beodolo kunye neshedyuli yemveliso
• Ukuthunyelwa: ukhetho lolwandle / lomoya / olukhawulezayo luyafumaneka
• Gcina kwindawo epholileyo, eyomileyo, nengena umoya kakuhle.
• Gcina isitya sivaliwe kakuhle kwaye sikhuselekile kumswakama.
• Kuphephe ukukhanya kwelanga ngqo, ubushushu, kunye nomlilo ovulekileyo.
• Landela isikhokelo se-SDS kwizinto ezingahambelaniyo.
