1. Irabha yemvelo (NR)
Ikakhulukazi i-hydrocarbon yerabha (i-polyisoprene), equkethe inani elincane lamaprotheni, amanzi, i-resin acid, ushukela kanye nosawoti we-inorganic.I-elasticity enkulu, amandla aqine kakhulu, ukumelana okuhle kakhulu kwezinyembezi kanye nokufakwa kukagesi, ukumelana nokugqokwa okuhle nokumelana nesomiso, ukucutshungulwa okuhle, ukuhlangana kalula nezinye izinto zokwakha, futhi kangcono kunama-rubber amaningi okwenziwa ngokusebenza okuphelele.Ukungalungi ukungakwazi ukumelana nomoya-mpilo ne-ozone, ukuguga okulula nokuwohloka;ukumelana kabiemafutheni nasezincibilikisini, ukumelana nokugqwala okuphansi kuma-acids nama-alkali, nokumelana nokushisa okuphansi.Ibanga lokushisa elisebenzayo: cishe -60℃~+80℃.Ukukhiqizwa kwamathayi, izicathulo zenjoloba, amapayipi, amateyipu, izingqimba ezivikelayo kanye nemisheko yezintambo nezintambo, nokunye okujwayelekile.imikhiqizo.Ifaneleka ngokukhethekile ukwakhiwa kwezinqamuleli zokudlidliza ezinyakazayo, izibambisi zokushaqeka kwenjini, izisekelo zemishini, izingxenye zokumiswa kwenjoloba-yensimbi, ama-diaphragm, nemikhiqizo ebunjiwe.
imikhiqizo yenjoloba
2. Irabha ye-styrene butadiene (SBR)
I-copolymer ye-butadiene ne-styrene.Ukusebenza kuseduze nalokho kwerabha yemvelo.Kuyinjoloba yokwenziwa yenhloso evamile enomphumela omkhulu okwamanje.Ibonakala ngokumelana nokuhuzuka, ukumelana nokuguga nokumelana nokushisa okudlula irabha yemvelo, futhi ukuthungwa kwayo kufana kakhulu kunerabha yemvelo.Okubi yilezi: ukunwebeka okuphansi, ukumelana nokugoba okungekuhle kanye nokumelana nezinyembezi;ukusebenza kabi kokucubungula, ikakhulukazi ukunamathela okungeyikho kanye namandla enjoloba aluhlaza aphansi.Intukuthelo yokusebenzaububanzi bemvelo: cishe -50℃~＋100℃.Isetshenziswa kakhulu esikhundleni senjoloba yemvelo ukwenza amathayi, amashidi enjoloba, amapayipi, izicathulo zenjoloba neminye imikhiqizo ejwayelekile.
3. Irabha ye-Butadiene (BR)
Iyirabha yesakhiwo se-cis eyakhiwe yi-polymerization ye-butadiene.Izinzuzo yilezi: ukunwebeka okuhle kakhulu nokumelana nokugqoka, ukumelana nokuguga okuhle, ukumelana nezinga lokushisa eliphansi kakhulu, ukukhiqizwa kokushisa okuphansi ngaphansi komthwalo oguquguqukayo, kanye nokubopha insimbi kalula.TUbubi bakhe amandla aphansi, ukungezwani kahle kwezinyembezi, ukusebenza kabi kokucubungula kanye nokunamathela ngokwakho.Ibanga lokushisa elisebenzayo: cishe -60℃~＋100℃.Ngokuvamile, isetshenziswa kanye nenjoloba yemvelo noma irabha ye-styrene-butadiene, ikakhulukazi ukwenza isondo.ifundeka, amabhande okuthutha kanye nemikhiqizo ekhethekile ekwazi ukumelana nokubanda.
4. Irabha ye-isoprene (IR)
Iwuhlobo lwerabha yesakhiwo se-cis eyenziwe nge-polymerization ye-isoprene monomer.Ukwakheka kwamakhemikhali kanye nesakhiwo esinezinhlangothi ezintathu kufana nenjoloba yemvelo, futhi ukusebenza kusondele kakhulu kunjoloba yemvelo, ngakho kubizwa ngokuthi imvelo yokwenziwa.irabha.Inezinzuzo eziningi zenjoloba yemvelo.Ngenxa yokumelana nokuguga, irabha yemvelo inokunwebeka kancane namandla kunenjoloba yemvelo, ukusebenza kabi kokucubungula kanye nezindleko eziphezulu.Ibanga lokushisa elisebenzayo: cishe -50℃~+100℃Ingathatha indawo yerabha yemvelo ukwenza amathayi, izicathulo zenjoloba, amapayipi, amateyipu kanye neminye imikhiqizo ejwayelekile.
5. I-Neoprene (CR)
Kuyi-polymer eyakhiwe yi-emulsion polymerization ye-chloroprene njenge-monomer.Lolu hlobo lwenjoloba luqukethe ama-athomu e-chlorine ku-molecule yawo, ngakho-ke uma kuqhathaniswa namanye ama-rubber ajwayelekile: ine-antioxidant enhle kakhulu, ukumelana ne-ozone, okungashi, ukuzicisha ngemuva komlilo, ukumelana nowoyela, ukumelana ne-solvent, ukumelana ne-asidi ne-alkali, ukuguga kanye negesi. ukumelana.Ukuqina okuhle nezinye izinzuzo;izakhiwo zayo ezingokomzimba nezemishini nazo zingcono kunerabha yemvelo, ngakho-ke ingasetshenziswa njengenjoloba yenhloso evamile noma irabha ekhethekile.Okubi okuyinhloko ukumelana nokubanda okungekuhle, amandla adonsela phansi amakhulu athile, izindleko eziphakeme ezihambisanayo, ukufakwa kukagesi okungekuhle, nokunamathela kalula, ukushisisa, kanye nokunamathela kwesikhunta ngesikhathi sokucubungula.Ngaphezu kwalokho, irabha eluhlaza ine-stabi embility futhi akulula ukugcina.Ibanga lokushisa elisebenzayo: cishe -45℃~＋100℃.Ikakhulukazi esetshenziselwa ukwakha amashethi ekhebula kanye nesembozo esivikelayo esihlukahlukene kanye nesembozo sokuzivikela esidinga ukumelana okuphezulu kwe-ozone nokumelana nokuguga okuphezulu;ukumelana kwamafutha namakhemikhaliamapayipi ama-ance, amateyipu nezindwangu zamakhemikhali;imikhiqizo yenjoloba engashi ezimayini ngaphansi komhlaba, kanye nokubumba okuhlukahlukene Imikhiqizo, izindandatho zokuvala, ama-gaskets, izinto zokunamathisela, njll.
