Acrylic emulsion
Hais txog cov khoom siv raw, kev ua lag luam acrylic tej zaum yuav txuas ntxiv mus tsis zoo rau lub lim tiam tom ntej; kev ua lag luam styrene tej zaum yuav tswj tau lub sijhawm; hais txog methamphetamine lossis cov disks tsis muaj zog. Kev ua tau zoo ntawm tus nqi rau kev ruaj khov yooj yim. Hais txog kev muab khoom, cov nyiaj tso cia pib ua lag luam yuav ruaj khov thiab zoo dua rau lub lim tiam tom ntej, thiab cov zis yuav tsis hloov pauv ntau. Qhov ua tau ntawm cov khoom muag ntau hauv qee lub Hoobkas tseem muaj. Hais txog kev thov, kev thov kawg tsis zoo li qhov xav tau, thiab tus lej ntawm cov xaj downstream tseem yuav tswj tau qib nruab nrab qis. Nws xav tias kev ua lag luam acrylic emulsion tseem yuav sib tham txog qhov tseem ceeb ntawm kev xa khoom.
Cov nqi ntawm cov khoom siv tseem ceeb ntawm cov tshuaj pleev xim tau sib txawv, nrog rau cov nqi ntawm N-butanol, Neopentarglycol, Xylene thiab lwm yam khoom nce siab, tab sis cov nqi ntawm epoxy resin, MDI, butyl acrylate thiab cov khoom lag luam cuam tshuam hauv cov saw hlau kev lag luam txuas ntxiv poob qis, thiab qhov sib txawv poob qis tau nthuav dav.
Neopentyl glycol/Isobutyraldehyde:Kev lag luam neopentylene glycol hauv tebchaws nce siab, tus nqi khoom siv raw nce me ntsis, kev txhawb nqa tus nqi nce siab, daim ntawv cog lus neopentylene glycol tau ua tiav ntau heev, qhov chaw nruj, tus nqi lag luam qis dua txav mus rau sab saud, tab sis cov chaw tsim khoom polyester resin downstream feem ntau ua raws li, cov khoom muag raug kev nyuaj siab, thiab kev ua raws li kev lag luam tsis txaus. Txog tam sim no, kev lag luam neopentylene glycol hauv tebchaws yog 10,500-10,800 yuan / ton. Tus nqi Isobutyral 7600-7700 yuan / ton.
Cov Lus Qhia Txog Butyl Acrylate:Kev lag luam butyl acrylate poob qis, nrog rau tus nqi poob qis ib feem ntawm qhov kawg ntawm kev yuav hauv qab, tab sis qhov kev lag luam tiag tiag rau tus nqi qis. Txog rau tam sim no, 8,700-8800 yuan / ton hauv kev lag luam sab hnub tuaj Tuam Tshoj, tam sim no kev thauj khoom kev lag luam tsawg dua 5%. Tab sis vim tsis muaj kev thov, kev lag luam butyl acrylate kev hloov pauv tseem ceeb tsawg, qhov ntim ntawm kev lag luam tam sim no tsis loj. Tsis ntev los no, kev lag luam acrylic tau tswj hwm kev poob siab.
Epoxy resin/Bisphenol A/ Epichlorohydrin:Tus nqi ntawm cov tshuaj epoxy hauv tsev tseem poob qis, East China kua epoxy resin nqi poob qis mus rau 13500-14200 yuan / ton; Huangshan khoom epoxy resin 13400-13900 yuan / ton. Cov khoom siv raw ntawm epoxy resin bisphenol A thiab epichlorohydrin txuas ntxiv poob qis hauv lub lim tiam, thiab qhov kev txhawb nqa ntawm cov tshuaj resin tsis muaj zog. Cov chaw tsim khoom tau ua kom muaj txiaj ntsig los ntawm kev nyuaj siab ntawm qhov chaw khaws cia, thiab kev txaus siab yuav khoom hauv qab tseem tsis muaj zog. Nrog rau tus nqi poob qis, cov neeg ua haujlwm tsis ntseeg siab rau kev ua lag luam yav tom ntej, cov tuam txhab kawg koom nrog kev yuav khoom kom tswj tau qhov kev thov me me, qhov chaw ntawm lub ntiajteb txawj nqus tsis muaj zog, nws xav tias cov tshuaj epoxy hauv tsev nyob rau hauv huab cua nyuaj siab yuav txuas ntxiv poob qis.
