Polyisobutylene (PIB)yog ib tug verstile synthetic polymer siv nyob rau hauv ntau kev lag luam. Nws los nyob rau hauv nyias lub cev hnyav molecular - siab thiab qis - uas cuam tshuam rau nws cov khoom thiab cov ntawv thov.
1. Dab tsi yog molecular hnyav?
Molecular hnyav hais txog qhov loj me lossis ntev ntawm cov saw polymer.
- Siab molecular hnyav pib: ntev polymer chains, tus qauv hnyav.
- Tsawg molecular hnyav pib: cov saw luv, sib dua thiab haus dej ntau.
Lub Koom Haum Rau Lub Cev
Qhov sib txawv feem ntau yog cov lus dag hauv lawv lub cev. Tsawg molecular phaus poly poly isobutylene feem ntau muaj nyob ua kua viscous. Nws ntws tau yooj yim dua, zoo ib yam li tuab zib ntab, thiab tuaj yeem nchuav lossis nqus nrog cov txheeb ze yooj yim. High molecular hnyav pib, ntawm qhov tod tes, feem ntau yog rubbery stuff. Nws muaj cov ntawv nyeem ruaj khov thiab tuav nws cov duab, zoo li ib qho ntawm cov roj hmab muag.
Cov yam ntxwv ua tau zoo
Tsawg molecular hnyav poly poly (isobutylene) muaj cov solubility zoo nyob rau hauv ntau cov kuab tshuaj thiab muaj qis viscosity. Nws feem ntau siv los kho cov khoom ntws ntawm cov khoom lag luam. Piv txwv li, nws tuaj yeem ua cov roj roj yeeb ntws ntau dua li qhov kub thiab txias. High molecular hnyav pib, txawm li cas los xij, muaj elasticity zoo, durability, thiab kev tawm tsam hnav thiab kua muag. Nws tuaj yeem tiv thaiv lub siab ntsuas thiab huab tsis muaj qhov yooj yim.
Daim Ntawv Thov
Tsawg molecular phaus polyisobutylene feem ntau siv los ua cov kev ntxiv hauv cov khoom lag luam xws li cov nplaum, uas nws txhim kho cov nplaum sib kis thiab pab cov nplaum. Nws kuj tau siv nyob rau hauv qee cov roj roj ntxiv los txhim kho kev ua tau zoo. Siab molecular hnyav pib ci rau hauv cov ntawv thov uas xav tau lub zog thiab hloov tau. Nws tau siv los ua gaskets, ntsaws ruaj ruaj rau hauv kev lag luam hauv tsheb, thiab cov khoom siv ruaj khov hauv cov khoom siv tsim.
Ob qho tib si loj thiab qis molecular hnyav polyisobutene pab cov haujlwm sib txawv. Siab MW PIB muaj lub zog, elasticity, thiab durability - zoo meej rau kev sib khi thiab cov ntawv thov. Tsawg MW PIB yog kua, yooj yim kom sib tov, thiab zoo tagnrho rau lubricating, softening, lossis hloov lwm cov ntaub ntawv. Xaiv cov qib kev ua kom muaj txiaj ntsig zoo thiab cov nqi ua haujlwm.
Peb tau muab cov khoom siv ua ke txhua xyoo puag ncig, tuaj yeem lav tau tias cov khoom lag luam zoo tuaj yeem lav rau cov neeg xa khoom, cov chaw thau khoom, koj puas txaus siab rau cov khoom no? Nyem rau hauv qab no los nug tam sim no thiab tau txais cov lus thiab kuaj tshwj xeeb! Peb yuav muab koj cov tshuaj acatic acid zoo tshaj plaws.
Gneebioyog ib qho kev lag luam tsim tawm hauv kev tshawb fawb thiab kev txhim kho, ntau lawm thiab muag khoom ntawm cov tshuaj lom neeg. Peb lub Hoobkas tau tsim tsa xyoo 2016 thiab nyob hauv Henan xeev, npog thaj tsam ntawm 3,600 square metres. Peb pab neeg muaj ntau tshaj 200 tus neeg. Tau ntau xyoo, tag nrho cov pab pawg tau txuas ntxiv txhim kho kom tau txais txiaj ntsig tiag tiag ntawm cov neeg siv khoom thiab tam sim no ua ib qho ntawm cov khoom lag luam cheem tsum hauv Henan xeev, Suav.
Peb cov khoom nrov muaj xws li polyisobutylene (pib), cawv (dencenep, etecene, thiab lwm yam. Peb vam tias yuav tsim kom muaj txiaj ntsig ntev thiab muaj kev sib koom tes sib txuas nrog cov phooj ywg ntxiv yav tom ntej thiab muab cov qhua tuaj noj mov nrog cov khoom lag luam zoo tshaj plaws thiab cov kev pabcuam zoo tshaj plaws.
Peb Qhov Zoo
1). Cov khoom noj me me me thiab ntim khoom muaj.
2). Muab COA, MSDS, Ntawv Pov Thawj Kev Noj Qab Haus Huv thiab Cov Ntawv Qhia Keeb Kwm.
3). Zoo ua ntej, kev pabcuam zoo tshaj.
