Isi ihe nkenkwonkwo mgbasa robabụ: silica gel, nitrile roba, neoprene,EPDM rọba, roba eke, fluoro roba na ndị ọzọ roba.
Njirimara anụ ahụ na-eji iguzogide mmanụ, acid, alkali, abrasion, elu na okpomọkụ dị ala.
1. rọba eke:
Sịntetik roba nkwonkwo nwere elu elasticity, elu elongation ike, ezigbo eyi na-eguzogide na oké ọkọchị, na ike ga-eji na okpomọkụ sitere na -60 ℃ ka +80 ℃. Usoro nwere ike ịbụ mmiri na gas.
2. Butyl roba:
A na-eji nkwonkwo roba na-eguzogide iyi na pipeline uzuzu na usoro ájá. Njikọ roba na-eyi na-eguzogide ọgwụ na corrosion bụ nkwonkwo roba ọkachamara nke emebere maka sistemụ desulfurization. Ọ nwere ezigbo nguzogide iyi, acid na alkali na-eguzogide, nguzogide corrosion, ma nwee ike kwụọ ụgwọ maka mgbasawanye axial, mgbasawanye radial, ngbanwe angular na ọrụ ndị ọzọ nke pipeline desulfurization.
3. Chloroprene roba (CR):
Njikọ roba na-eguzogide mmiri nke oke osimiri, nke nwere ezigbo ikuku oxygen na ozone, ya mere nguzogide ya dị mma karịsịa. Oke okpomọkụ na-arụ ọrụ: ihe dịka -45 ℃ ruo + 100 ℃, na mmiri mmiri dị ka isi ihe.
4. rọba nitrile (NBR):
Njikọ roba na-eguzogide mmanụ. Njirimara bụ ezigbo iguzogide mmanụ ụgbọala. Oke okpomọkụ na-arụ ọrụ: ihe dịka -30 ℃ ruo + 100 ℃. Ngwaahịa kwekọrọ na ya bụ: nkwonkwo roba na-eguzogide mmanụ, na nsị mmiri dị ka ọkara.
5. Ethylene propylene diene monomer (EPDM):
A na-ejikarị nkwonkwo rọba na-eguzogide acid na alkali, nke a na-eji acid na alkali na-eguzogide, na okpomọkụ dị ihe dịka -30 ℃ ruo + 150 ℃. Ngwaahịa kwekọrọ: acid na alkali na-eguzogide roba nkwonkwo, ọkara bụ nsị.
Fluorine roba (FPM) rọba nkwonkwo na-ekpo ọkụ na-ekpo ọkụ bụ usoro elastomer mmepụta ugbo nke e guzobere site na copolymerization nke fluorine nwere monomers. Njirimara ya bụ nguzogide okpomọkụ dị elu ruo 300 ℃.
Nhazi na njirimara arụmọrụ
N'ihe banyere ojiji, e nwere ụdị atọ nke EPDM roba (nke a na-achọkarị maka mmiri na-eguzogide mmiri, mmiri na-eguzogide mmiri, na ịka nká), rọba eke (nke a na-ejikarị maka rọba nke na-achọ naanị elasticity), butyl rubber (roba nke chọrọ ịrụ ọrụ nke ọma. ), rọba nitrile (roba nke chọrọ nguzogide mmanụ), na silicone (raba ọkwa nri);
A na-eji rọba akara eme ihe n'ọtụtụ ụlọ ọrụ dị ka antistatic, ire ọkụ, ngwa elektrọn, kemịkalụ, ọgwụ na nri.
A na-ekewa ihe nke nkwonkwo roba n'ụdị dị iche iche dabere na ihe eji eme ihe, dị ka rubber chloroprene, rubber butyl, fluororubber, EPDM roba, na roba eke. A na-eji nkwonkwo rọba na-agbanwe agbanwe eme ihe n'ọtụtụ ebe na njikọ pipeline dị iche iche, nwere njirimara arụmọrụ nke ntinye ujo, mbelata mkpọtụ, na nkwụghachi ụgwọ.
Ọrụ nke nkwonkwo roba dịgasị iche dabere na ihe eji eme ihe. Ihe dị iche iche na-arụ ọrụ na-agụnye fluororubber pụrụ iche na silicone roba, nke nwere nguzogide eyi, nkwụsị nrụgide, na oke okpomọkụ. Ọ nwere nguzogide mmanụ, acid na alkali resistance, oyi na okpomọkụ na-eguzogide, ịka nká na-eguzogide, wdg N'ihe gbasara nhazi, roba nwere ike ime ka ọ bụrụ ụdị dị iche iche nke nkwonkwo mgbasa roba.
