Polyisobutylene (pib)

Polyisobutylene (pib)Isina ruvara, isina kuravira, isina-chepfu yakajeka kana yeiyo-yepfumi chinhu, kupokana kupokana, kupokana kweOzone, ozid neAlkali kuramba uye mamwe makemikari kuita kwakanaka. Polyisobutylene isisina ruvara, isina kusimba, isina-toxico isoutylene chomolymer. Nekuda kwenzira dzakasiyana dzekugadzirira uye mamiriro ehunyanzvi, iyo molecular kemalbook huwandu hwePolyisobutginelene inosiyana munzvimbo dzakasiyana. Yakawanda yeiyo molecar Polyoisobutylene anoramba kuAcid, Alkali, munyu, mvura, ezono nekukwegura, uye ane mweya wakanaka uye kusimba kwemagetsi.

Makemikari Zvivakwa:isina ruvara kujekesa yeyero viscous yemvura kana elastic rubbery semisolid (yakaderera molecular uremu hwakapfava, hwakanyanya molecular huremu hwakaoma uye elastic). Zvese zvisina kusimba, zvinonhuhwirira kana zvishoma zvinonhuhwirira zvinonhuwira. Iyo avhareji melocular uremu ndeye 200,000 ~ 87 miriyoni. Soluble muBenzene uye DiisoButyl Chemicalbook, inogona kuve isinganzwisisike nePolyvinyl acetate, wax, etc., kushaya mvura, doro uye humwe humwe hunonwa. Inogona kuita shuma yegubhu ive nekunakisa kwakanaka pakudziya kwakadzika, uye ine imwe plasticity tembiricha yekudziya yekugadzira kupfupika kwePolyvinyl acetate kana ichitonhora, kupisa kwemamiriro ekunze kana ichinyorova kana ichinyorova kana ichinyorova kana ichinge yasangana nemuromo.

Zvishandiso:Pib inozivikanwa nekuda kwezvakanakisa zvinosimbisa uye zvinonamatira, zvinowanzoshandiswa mumheromani, marara, uye maSalalants. PIB Rubber-Senge Zvivakwa zvinoita kuti ive sarudzo yakanaka yekuisa chisimbiso uye zvinosanganisira mashandisirwo, sezvo zvichibatsira kupa chisungo chakasimba uye chakasimba mune akawanda marongero. Pamusoro pekushandiswa kwayo kunoshanda, pib inowanzoshandiswa mune cosmetics uye zvinhu zvega zvega nekuda kwezvinhu zvakanakisa zvekunyanyisa solubility. Iyo chinhu chinowanzobatanidzwa pamwe nezvimwe zvinosanganiswa kuti ugadzire zvigadzirwa zvine ruzivo rwakasiyana uye kunzwa.

Pib ine huwandu hwakawanda hwekushandisa muindasitiri yechikafu zvakare. Chinhu icho chinowanzoshandiswa seanotenderedza, stabilizer, uye emulsifier mune zvekugadzira chikafu. PIC inogona kubatsirawo kuvandudza chimiro uye kusawirirana kwezvigadzirwa zvakaita se ice cream, chewing gamu, uye zvinhu zvakabikwa. Iko kuwanda kwe pib kunoita kuti ive chinhu chakakosha kune vagadziri muindasitiri yechikafu.

PIM inowanzoshandiswa zvakanyanya muindasitiri yekurapa. Iyo midziyo isiri-ine chepfu inoita kuti ive yakakodzera kushandiswa mune zvekurapa application. Iyo chinhu chinowanzo shandiswa sedutu pasi mumasenduru, pamwe nechinhu chakanyorwa mumishonga yakawanda. Hydrophobic yakasikwa inobatsira kuomerera paganda, ichiita kuti ibatsire mukugadzirwa kwekurapa.

Hunhu:Polyisobutylecene ane makemikari emagetsi emagetsi erdrocarbon makomputa, uye divi reketani rejira rakanyatso kugoverwa kugovera, iyo yakasarudzika polymer. Iyo Aggregation State uye zvivakwa zvePolyisobutylene inoenderana neyakaomeswa nehuremu hwehuremu uye molecular uremu kugoverwa. Kana viscosity avhareji yemulecular uremu ari muhuwandu hwe70000 ~ 90000, purisobutylene shanduko kubva pakushandura mvura kusvika kune elastic solid. Kazhinji, maererano nehukuru hwemanyorerwe wePolyisobutylene inokamurwa muzvikamu zvinotevera: Low molecular uremu Polyisobutylene (nhamba yepakati suremu = 200-10000); Pakati pemepu molecular uremu polyisobutylene (nhamba yepakati molecular uremu = 20000-000); Yakakwira Molecular uremu Polyisobutylene (nhamba yepakati molecular uremu = 75,000-600,000); Ultra yakakwira molecular uremu polyisobutylene (nhamba yeavhareji molecular uremu hukuru kupfuura 760000).

1. Mhepo yakasimba

Imwe yehunhu hwakatanhamara hwePolyisobutylene ndiye wakanyanya kunaka mhepo. Nekuda kwekuvapo kwemaviri ekutsiva methyl methyl mapoka, iyo molecular keteni kufamba inononoka uye iyo yemahara vhoriyamu idiki. Izvi zvinoguma zvakaenzana zvakashata zvakabatana uye kufungidzira kwegesi.

2. Solubility

Polyisobutylene inokwira mualiphatic hydrocarbon, peturu, naphthe, mashlene oiri, chlorinated hydrocarbon uye kabhoni monosulmide. Zvidimbu zvakazara mumachira ekutakura uye cheki, kana kuzvimba muzvipenga, monomers, makiromita uye mwero wekuzvimba, iyo miriwo yekuzvimba kweiyo solvent carbon ketani kureba; Insoless muzvipfuyo zvebwe (esthanol, ethanol, isopropyl doro, ethylene glycol naCotheryl

3. Kemical Resistance

Polyisobutylene anoramba kuAcid naAlkali. SaAmonia, hydrochloric acid, 60% hydrofluorgicic acid, 85% sodium mvura, 800} sulfutic acid + 14% nitric acid yekukanganisa, zvakadaro, iyo haigoni kuramba kugura kwehukuru hwehupfumi, kupisa kwehupfumi hwevakadzi (senge 60% Potassium Permonganate), dzimwe hadzi dzakaomeswa organic acids (dzakadai se 373k acetic acid) uye fluorine, chlorine, rerence).

Kurongedza: 180kg chigubhu

Chengetedza: Chengetedza mune inotonhorera, yakatonhorera, nzvimbo yakaoma nekudzivirirwa kwezuva panguva yekufambisa.

Mukupedzisa, pib chinhu chakakosha nechero huwandu hwezvigadzirwa mumaindasitiri akasiyana siyana. Yayo yakawedzera chisimbiso uye inonamatira zvivakwa, pamwe nekushongedza kwayo uye kuwanda, ita kuti ive yakakodzera kune zvinoshandiswa mukati menguva yekuzora, kuchengetwa kwako, chikafu, uye maindasitiri ekurapa. Semutengesi anotungamira wePib, isu takatsaurirwa kupa vatengi vedu nezvigadzirwa zvepamusoro zvemhando yepamusoro uye masevhisi kuti tisangane nezvavaindida zveindasitiri.
