Methyl 4-chloroacetoacetate

Umuriro ariko ntugurumana, ufite impumuro idasanzwe ya alkyl phenol.Gushonga muri alcool, ester, alkane, aromatic nizindi miti ikungahaye, nka Ethanol, acetone, butyl acetate, lisansi, toluene, gushonga mumuti ukomeye wa alkali.Hamwe nibiranga ibintu bisanzwe bya fenolike, uhuye numucyo, ubushyuhe, guhura numwuka, ibara ryimbitse.

Mu nganda zikora inganda, p-tert-butylphenol ikoreshwa cyane cyane mu gukora amavuta ya elegitoronike ya fenolike, gucapa wino, flame retardant, nibindi.Mu rwego rwibikoresho byo guhuza ibiryo, p-tert-butyl fenol ikoreshwa kenshi mugukora ibisigazwa bya polikarubone, kandi birashobora no gukoreshwa muguhuza inyongeramusaruro kubikoresho byo guhuza ibiryo.

1. Umutekano wa PTBP
PTBP ntabwo ifite uburozi bwa geneti na kanseri, kandi uburozi bukabije bwo mu kanwa bwimbeba zifite LD50> 2000 mg / kg ni uburozi buke.Ifite uburakari buringaniye kuruhu rwurukwavu.Agaciro ka NOAEL kangana na 60 mg / kg · bw / kumunsi byagaragaye mu mbeba zimwe zifite guhumeka bidasanzwe cyangwa bigoye no kugabanuka kwa plasma albumin mugihe cy'iminsi 42 isubiramo umunwa.Hagati aho, PTBP ni iy'imiterere ya estrogene ya fenolike, kandi agaciro ka NOAEL k'uburozi bw'imyororokere y’imbeba ni 200 mg / kg · bw / umunsi, byerekana uburozi bw’imyororokere.Kubwibyo, PTBP ifite ingaruka zimwe kandi ikwiye kwitabwaho.

2. Gukoresha PTBP mubikoresho byo guhuza ibiryo
PTBP ni ibikoresho fatizo byimiti bitaboneka cyangwa bidahari mubikoresho byo guhuza ibiryo.Irashobora gukoreshwa nkibikorwa bya polymer cyangwa inyongera.
Muri polymers, zikoreshwa cyane nka monomer itangira kandi ikarangiza-gufunga.Kurugero, mugusiga polymers ishingiye, formaldehyde, fenol, p-tert-butylphenol polymers na polymers ya formaldehyde, fenol, p-tert-butylphenol na n-butanol polymers hamwe na p-tert-butylphenol nka monomer no gutangira.Poly4,4 '-isopropyl diphenyl karubone ya plastike ifunze hamwe na p-tert-butylphenol muri polymers.
Nka nyongeramusaruro, irashobora gukoreshwa kugirango igabanye ibiri muri hydroxyl ya nyuma muri coatings no kuzamura ibicuruzwa.Muri plastiki irashobora gukoreshwa nka antioxydeant, nko kubikoresho bya PS byangiza ibiryo bya pulasitiki nibicuruzwa, kugirango ubuze ibicuruzwa mu musaruro cyangwa gukoresha okiside yumuriro, umuvuduko wa fotooxidation, gutinda kwangirika, gusaza kwumuhondo, no kongera serivisi ubuzima bwibicuruzwa.

P-tert-butylphenol ifite antioxydeant kandi irashobora gukoreshwa nka stabilisateur ya reberi, isabune, hydrocarbone ya chlorine na fibre igogora.Uv ikurura, imiti yica udukoko, reberi, irangi nindi miti igabanya ubukana.Kurugero, ikoreshwa kuri resin ya polyikarubone, tert-butyl phenoline resin, epoxy resin, polyvinyl chloride, styrene stabilisateur.Byongeye kandi, ni nibikoresho fatizo byica udukoko twangiza imiti, imiti yica udukoko na acariside, impumuro nziza nuburinzi bwibimera.Irashobora kandi gukoreshwa nko koroshya, gushonga, kongeramo amarangi no gusiga amarangi, antioxydeant yamavuta yo gusiga, amavuta yangiza amavuta hamwe ninyongeramusaruro ya lisansi.

Ibindi bikorwa:
.Muri chloroprene yometseho ivanze 10-15% byibicuruzwa, kugirango ibone ibishishwa byoroshye, ubu bwoko bwamavuta bukoreshwa cyane cyane mubwikorezi, ubwubatsi, ubwenegihugu, gukora inkweto, nibindi. Mu gucapa wino, birashobora gukoreshwa muguhindura rosin, offset gucapa, gufotora bigezweho nibindi.Muri varish ya insulation, irashobora gukoreshwa muri coil dip varnish na laminate varnish.
.
(3) Byakoreshejwe kuri epoxy resin, guhindura xylene;Nka polyvinyl chloride stabilisateur, surfactant, imashini ya UV.
(4) Hamwe na antioxydeant, irashobora gukoreshwa nka reberi, isabune, hydrocarbone ya chlorine na stabilisateur ya nitrocelluloose.Nibikoresho fatizo byica udukoko (imiti), acaride acaride (pesticide) hamwe nubushakashatsi bwo kurinda ibimera, impumuro nziza, resinike, kandi birashobora no gukoreshwa nk'ibyoroshya, ibishishwa, irangi hamwe n’inyongera.Irashobora kandi gukoreshwa nkibigize demulsifier kumurima wamavuta hamwe ninyongera kumavuta yimodoka.
