I-PolyisobityLene (PIB)

I-PolyisobityLene (PIB)Ingabe into engenabala, engenamkhawulo, engenamkhawulo, ukumelana nokushisa, ukumelana nokushisa komoya, ukumelana nomoya-mpilo, ukumelana kwe-ozone, ukumelana kwesimo sezulu, ukumelana kwe-alkali kanye namanye amakhemikhali ukusebenza okuhle. I-PolyisobityLelene iyi-asopolylener ye-homopolymer engenasici, engenasisekelo, engenalo ubuthi obunobuthi. Ngenxa yezindlela ezahlukahlukene zokulungiselela kanye nezimo zobuchwepheshe, inani lamakhemikhali le-molefanelar le-polyisobutylene liyahlukahluka. Iningi lesisindo se-molecular somkhiqizo lifinyelela ngaphezu kwe-10,000 kuya ku-200,000 lizoguqulwa lisuka koketshezi oluqinile liye ku-semi-solity, bese kuthi ukuguqukela ku-elastomer enjoloba. I-PolyisobityLelene imelana ne-acid, alkali, usawoti, amanzi, i-ozone nokuguga, futhi inokuqina komoya okuhle nokufakwa kukagesi.

Izakhiwo zamakhemikhali:Umbala ongenamibala wokukhanyisa uketshezi oluphuzi lwe-viscous noma i-anwestic herury semisolid (isisindo esiphansi samangqamuzana sithambile se-gelatinous, isisindo esiphakeme se-molecular yi-ductile ne-elastic). Yonke iphunga elingenamodi, elingenamonali noma elinophunga elincanyana. Isisindo samangqamuzana esijwayelekile singama-200,000 ~ 87 million. Incibilika e-benzene ne-diisobuttyl chemicalbook, ingaba ukungazi kahle nge-polyvinyl acetate, i-wax, njll. Kungenza ushukela we-gum uthambile kakhulu emazingeni okushisa aphansi, futhi unesimo esithile sokushisa esiphakeme sokushisa okuphezulu kokwenza ukushiyeka kwe-polyvinyl acetate lapho kuyanda lapho ihlangabezana nokushisa komlomo.

Izicelo:I-PIB yaziwa ngokubekwa kwayo okuhle nokunamathela ngokunamathela, okuvame ukusetshenziswa ezinamatheli, ukumboza kanye nama-sealants. Izakhiwo ezifana ne-ruble ka-pib zenza kube yisinqumo esihle kakhulu sokufaka uphawu nokubopha izibopho, ngoba kusiza ukuhlinzeka ngesibopho esiqinile nesihlala isikhathi eside kuzilungiselelo eziningi. Ngaphezu kokusetshenziswa kwayo okusebenzayo, i-PIB isetshenziswa kakhulu kwizimonyo kanye nezinto zokunakekelwa komuntu ngenxa yezakhiwo zayo ezinhle kakhulu ze-solubity. Into ivame ukuhlanganiswa nezinye izithako zokwakha imikhiqizo ngokuthungwa okuhlukile futhi uzizwe.

I-PIB inezinhlobonhlobo zezicelo embonini yokudla futhi. Into evame ukusetshenziswa njenge-smighter, i-stabilizer, kanye ne-emulsifier ekudleni okusetshenzwe. I-PIB ingasiza futhi ukuthuthukisa ukuthungwa nokuvumelana kwemikhiqizo efana ne-ayisikhilimu, ukuhlafuna insini, nezimpahla ezibhakiwe. Ukuguquguquka kwe-PIB kwenza kube yisithako esibalulekile sabakhiqizi embonini yokudla.

I-PIB nayo isetshenziswa kabanzi embonini yezokwelapha. Izakhiwo ezingezona ezingezona ezinobuthi zikwenza ilungele ukusetshenziswa kwizicelo zezokwelapha. Into ivame ukusetshenziswa njenge-stabilizer ekugomeni, kanye nesithako emithini eminingi. Imvelo ka-Pib Hydrophobic iyasiza ukunamathela esikhunjeni, okwenza kube lusizo ekukhiqizweni kwezikhangiso zezokwelapha.

Izici:I-PolyiSOBUTYLELENE inezindawo zamakhemikhali zamakhemikhali agcwele ama-hydrocarbon, futhi iqembu le-methyl liseceleni ukusatshalaliswa okulinganayo, okuyi-polymer eyingqayizivele. Izwe elihlanganisiwe nezindawo zePolisobutylene kuncike kusisindo sayo samangqamuzana kanye nokusatshalaliswa kwesisindo kwamamolekyuli. Lapho isisindo se-viscosity isisindo se-molecular sisezingeni le-70000 ~ 90000, i-polyisobutlene iguqula kusuka kuluketshezi oluguqukayo lube lukhuni oluningi. Ngokuvamile, ngokosayizi wesisindo se-molecular of polyisobutleneenene kwehlukaniswe ochungechungeni olulandelayo: isisindo esiphansi se-polyisobutlelene (isisindo se-molecular molecular = 200-10000); Isisindo esiphakathi se-molecular polyisobutylene (isisindo se-molecular aphakathi = 20000-45,000); Isisindo esiphakeme se-molecular polyisobutylene (isisindo samangqamuzana aphakathi = 75,000-600,000); I-Ultra High Molecular polyisobitylene (inani lesisindo esijwayelekile se-molecular likhulu kune-760000).

1. Ukuqina komoya

Enye yezimpawu ezivelele ze-polybusotylene iyindlela yokuqina yomoya yayo enhle kakhulu. Ngenxa yokuba khona kwamaqembu amabili we-methyl angena esikhundleni, ukunyakaza kwama-molecular chain kuhamba kancane futhi ivolumu yamahhala lincane. Lokhu kuphumela ekunciphiseni okuphansi kwe-coefficity kanye negesi.

2. I-Solubity

I-PolyiSObutLelene iyanyibilika ku-aliphatic hydrocarbon, i-aromatic hydrocarbon, uphethiloli, uNaphnene, uwoyela wamaminerali, i-hydrocarbon ye-hydrocarbon kanye ne-carbon monosulfide. Inqola ngokwengxenye ku-alcohols ephezulu kanye noshizi, noma ukuvuvukala ngotshwala, izitha, amamomone, ama-ketones nakwamanye ama-sol kanye namafutha okuvuvukala, izinga lokuvuvukala likhuphuka ngokunyuka kobude be-solvent carbon chain ubude bodwa; I-insoluble ngotshwala obuphansi (njenge-methanol, i-ethanol, i-isopropyl Alcohol, i-ethylene glycol kanye ne-coenglene glycol), ama-ketones (acetone, i-methyl ethyl ketone) ne-glacial acetic acid.

3. Ukumelana Kwamakhemikhali

I-PolyisobityLelene imelana ne-acid ne-alkali. Njenge-ammonia, i-hydrochloric acid, 60% i-hydrofluoric acid, i-65% ye-phosphoric acid, i-8%} sulfuric acid, noma kunjalo, it %%% ayikwazi ukumelana nokuguguleka kwama-oxidants aqinile, ama-oxidant ashisayo abuthakathaka (njenge-60% potassium I-PermangaManate), amanye ama-organicici acid ashiselelayo ashisayo (njenge-373k acetic acid) nama-halogen (ama-fluorine, chlorine, ugwadule).

Ukupakisha: 180kg Drum

Isitoreji: gcina endaweni epholile, enomoya, esomile ngokuvikelwa kwelanga ngesikhathi sokuhamba.

Ekuphetheni, i-PIB iyinto ebalulekile enobuningi bezicelo ezimbonini ezahlukahlukene. Izakhiwo zayo ezinhle kakhulu zokubekwa uphawu nokunamathela, kanye ne-solubility yayo kanye nokuguquguquka, kwenze ilungele izinhlelo zokusebenza ngaphakathi kwezimonyo, ukunakekelwa komuntu siqu, ukudla kanye nezimboni zezokwelapha. Njengomhlinzeki oholayo wePib, sizinikezele ekuhlinzekeni amakhasimende ethu ngemikhiqizo nezinsizakalo ezisezingeni eliphakeme kakhulu ukuze ahlangabezane nezidingo zabo zemboni.
