Umukozi PVI y'Abakozi

Imvugo:

Umukozi wo kudatera inkunga PVI(CTP)

Gusobanura:

Ikoreshwa ry'ikoreshwa:

(1) PVI nyinshi zikoreshwa mu gutuma umutekano wo gukora neza no kugabanya ugutakaza ubushobozi bwo gukora ({1}}(2) urugero rwo gukora neza n’ubuhinga bwa PVI bivana n’ubwoko bw’umurongozi n’ingero y’ikibiriti ikoreshwa. vyabonetse ko igikorwa c’imipira y’amazi ari co gihambaye kuruta ibindi vyose mu nzira ya sulfonamide sulfide isanzwe y’amazuku. 0.1 PHR PVI itera imbere mu gukingira umutekano wo gutera imbere (guteka) n’ibice 30% ku mupira w’amazi n’ibice 10% ku mupira w’amaguru wa styrene, kandi gutera imbere muri rusangi bihuye n’ingero.

(3)PVI ni ngirakamaro cane ku bikoresho vyose bishobora guhinduka nka SBR, NBR, IR, IIR, EPDM na CR, kandi irakora ku mupira w’amazi ({1}}PVI ishobora gusubirira NDPA n’igipimo ca kera 4:1 n’ibintu vya kera nk’aside z’ibinyabuzima (e{4}} gusubirira NDPA na 0{{8}2phr PVI . na 1.0phr).

(4) nk’amasegonda 45 imbere y’uko urugendo rwo guvanga ruhera, rwihuta, rw’ikibiriti na PVI rwongeweko . Kenshi, uruziga rw’inzira zibiri rushobora guhindurwa mu nzira y’uguvanga kw’inzira imwe kugira ngo umuntu azigame 30% vy’inguvu n’igihe, hanyuma bikajanwa kugira ngo bikomeze gukonjesha vyihuta.Ingero ya PVI ikenewe iva ku bushuhe, ariko akenshi 0.5 PH. Ingero ya 0.1phr irabereye kugira ngo itere imbere cane igiti c'umukaraba

Ugushikama kw'ububiko bw'ububiko bw'ibicuruzwa{0}}

(5) kubera uburenganzira bwo guhindura ibintu (guteza), ibikoresho vy’imipira vyatunganijwe mu ruganda ntibishobora gusubirwamwo, bikaba bituma imyanda y’amasigarira y’amasigarira y’amasigarira{1}}Iryo cegeranyo, umubare ukwiye wa PVI ishobora kwongerwa kugira ngo ivangane n’ibikoresho bishasha vy’imipira, hanyuma ibikoresho vy’imipira vy’imipira vya kera bishobora kwongerwako. Gukoresha ibipimo vya PVI birakora neza iyo ari 0.3 PHR.

(6)PVI ishobora kandi gukoreshwa mu buryo bwihuta kandi bworoshe bwa kera, kandi igihe ca mbere c’uguhindura ubumara gitegekanijwe n’ingero y’ibikorwa vya PVI{1}}

(7) PVI itegerezwa gukoreshwa mu buryo bubereye kandi birakenewe ko umuntu agabanya ingano kugira ngo yirinde kudahagije .Ikiranga PVI ni uko hariho isano ry’umurongo hagati y’igikorwa cayo co hejuru n’iterambere ry’umutekano wo gutunganya n’ingero yaryo .

Ibisabwa vy'ikoreshwa:

Ikoreshwa cane mu bikoresho bitandukanye n’ibikoresho bishobora gusenyuka.Ishobora gutuma umutekano w’imipira ugenda neza (igihe co guhindura ibintu mu buryo bwa mbere), ingaruka nke canke nta ngaruka ku bindi bikorwa vyo gukora canke ibikorwa vy’imikorere.

Imisoro ishushe: pvi, Ubushinwa, umuhinguzi, abagurisha, uruganda, igiciro, ubudandaji bw’imipira, umunyu w’imipira, umuti w’imipira uteguwe
