Dab tsi yogPolyisobutylene (PIB) polymer?
Pib muaj peb pawg: low molecular weight pib, nruab nrab molecular weight pib thiab high molecular weight pib.
- Tsawg molecular hnyav pa thiab siab reactive PIBs yog pob tshab kua polymers siv raws li viscosity modifiers los yog plasticizers nyob rau hauv ib tug ntau yam ntawm kev siv xws li lubricants, adhesives thiab sealants, rubbers thiab yas, cosmetic formulations, thiab lwm yam. Lawv cov yam ntxwv tseem ceeb yog molecular hnyav (xws li los ntawm 280 mus rau 6.000) thiab kinematic viscosity (xws li 2 txog 40. 000 cSt ntawm 100ºC).
- Qhov nruab nrab thiab siab molecular hnyav PIBs yog ib nrab ntawm cov khoom siv polymers uas yog siv los ua cov khoom siv ntxiv lossis cov khoom siv tseem ceeb hauv ntau cov qauv, suav nrog cov roj nplaum, cov nplaum thiab cov sealants, zom cov pos hniav, cov khoom siv thiab cov khoom siv hluav taws xob. Lawv cov yam ntxwv tseem ceeb kuj yog lawv qhov hnyav molecular, uas nyob ntawm 30.000 mus rau 3.000.000 thiab qee zaum qhia hauv Staudinger's Performance index, los ntawm 20 txog 600 cm3 / g.

Polyisobutylene (PIB) polymer siv rau dab tsi?
- Adhesives thiab Sealants: PIB txhim kho cov kav ntev thiab kev ua haujlwm ntawm cov nplaum thiab cov sealants rau ntau yam kev siv.
- Wax blends thiab lubricants: Nws plays lub luag haujlwm tseem ceeb hauv kev txhim kho lubricant efficiency thiab ncua lub neej txhua yam.
- Laminating thiab txheej: PIB cov khoom zoo heev ua rau nws zoo tagnrho rau lamination thiab txheej.
- Roofing membranes: PIB's elasticity thiab lub zog ua rau nws xaiv vov tsev.
- Polyolefin thiab Rubber Blends: Thaum siv hauv kev sib xyaw, nws txhim kho kev ua haujlwm ntawm polyolefins thiab roj hmab.
