I-Polyisobutylene CAS 9003-27-4
I-Polyisobutylene (PIB, CAS 9003-27-4) iyi-polymer eqondile egcwele etholakala nge-cationic polymerization ye-isobutylene monomer. Ayinawo ubuthi, ayinaphunga, izinzile kakhulu, ayingeni moya kakhulu, ivikela kakhulu, futhi isimo sayo siyashintsha kusuka kuketshezi oluqinile → oluqinile kancane → i-elastomer yerabha njengoba isisindo sama-molecule sikhula.
Imelana kakhulu nokuguga kanye nokuqina kwamakhemikhali
Ukugcwala kweketanga eligcwele: ukumelana nokushisa, umoya-mpilo, i-ozone, imisebe ye-ultraviolet, ama-acid, ama-alkali kanye nosawoti, akuwohloki noma kuqhekeke isikhathi eside
Ukuqina kokushisa: kungasetshenziswa isikhathi eside ku--50℃ kuya ku-150℃, nge-flash point ephezulu kanye nokusha okuphansi
Umoya ophezulu + ukuvikela okuphezulu + ukungena okuphansi
Umoya onamandla kakhulu: izakhiwo ezinhle kakhulu zokuvimbela amanzi, igesi kanye nomusi, ezingcono kakhulu kunerabha evamile
Ukufakwa kahle kukagesi: ukumelana nomthamo ophezulu, ukulahleka okuphansi kwe-dielectric, okufanelekela izintambo/ukuvalwa kukagesi
Ukuhambisana okuphephile nokungabuthi + okubanzi
Izinga lokudla le-FDA: alinabo ubuthi, alicasuli, lingasetshenziswa ekuhlafuneni itshungama, izimonyo, nezinto ezisizayo zemithi
Ihlangana nama-hydrocarbon/irabha/i-resin: kulula ukuyihlanganisa nokuyiguqula, ithuthukisa ukujiya, ukuguquguquka kanye nokumelana nesimo sezulu.

Isisindo sama-molecule esiphansi i-PIB (i-Mw < 10,000, uketshezi oluqinile)
Izithasiselo zikaphethiloli/izithasiselo zikaphethiloli: ukuqina, ukuvimbela ukwakheka kwe-gelling, ukuvimbela ukuguguleka, ukuvala kanye nokuvimbela ukuvuza
Izinto zokunamathisela/zokuvala: ingcina ezwela ukucindezela, irabha ye-butyl eguquliwe, ingcina engangeni manzi, ingcina yamafasitela emoto
Izimonyo / imikhiqizo yobuhle: i-lipstick / i-lip balm (efaka umswakama ngaphandle kokugcoba), ukhilimu (ovala umswakama bese wenza ulwelwesi), othatha indawo ye-squalane
Ukudla: isisekelo setshungama (ukuthuthukisa ukuhlafuna, ukuvimbela ukunamathela kwamazinyo)
2) Isisindo sama-molecule esimaphakathi i-PIB (i-Mw 10,000 - 100,000, irabha eqinile/ethambile kancane)
Ukuguqulwa kwerabha: i-acrylonitrile / chloroprene rubber plasticizer, okuthuthukisa ukumelana nowoyela kanye nokuqina komoya
Amakhebula/izintambo: ukufakwa kokushisa, igobolondo elingangeni manzi, ukugqoka okumelana nesimo sezulu
Izembozo / i-asphalt: isembozo esilwa nokugqwala, ukuguqulwa kwe-asphalt (elwa nokuqhekeka, elwa nokuguga)
3) Isisindo sama-molecule aphezulu i-PIB (i-Mw > 100,000, i-elastomer efana nerabha)
Irabha ekhethekile: ithayi langaphakathi elingangeni moya kakhulu, ingxenye yokuvala i-vacuum, i-gasket yokulwa nokuguga
Ukuguqulwa kwepulasitiki: Ukuqinisa i-PP/PE, okuthuthukisa ukumelana nomthelela kanye nokumelana nesimo sezulu
• Ukupakisha Okujwayelekile: 25 kg/isikhwama; 25 kg/isigubhu
• I-MOQ: kufanele iqinisekiswe ngokwebanga nendawo oya kuyo
• Isikhathi Sokuhola: kuzoqinisekiswa ngobuningi be-oda kanye nesheduli yokukhiqiza
• Ukuthunyelwa: izinketho zolwandle / zomoya / ze-express ziyatholakala
• Gcina endaweni epholile, eyomile, futhi enomoya omuhle.
• Gcina isitsha sivaliwe kahle futhi sivikelekile emswakama.
• Gwema ukukhanya kwelanga okuqondile, ukushisa, kanye nomlilo ovulekile.
• Landela isiqondiso se-SDS ngezinto ezingahambisani.
