Ukwehla kwentengo kawoyela emhlabeni wonke kuye kwenza imakethe yemboni yamakhemikhali yaba buthaka. Ngokombono wemvelo yasekhaya, yize ibhange eliphakathi limemezele ukwehla kwafika ku-0.25%, isidingo esingezansi sincane kakhulu kunalokho obekulindelwe. Izindleko zemakethe yamakhemikhali zilinganiselwe, isidingo asisheleli, futhi imakethe yemboni yamakhemikhali ibuthakathaka.
Intengo yemakethe yaseMpumalanga China ye-bisphenol A ingu-9450 yuan/ton, kanye nokwenyuka okungu--1.05%;
Intengo yemakethe ye-epichlorohydrin eMpumalanga yeShayina ingu-8500 yuan/ton, ikhuphuke ngo-1.16%;
Intengo yemakethe yokuhlanzwa kwamanzi ye-Epoxy resin eMpumalanga China ingu-13900 yuan/ton, ikhuphuke ngo-2.11%;
Intengo yemakethe ye-PO Shandong 9950 yuan/ton, ikhuphuke -4.78%;
Intengo yemakethe ye-polymerization MDI East China ingu-15500 yuan/ton, ikhuphuke ngo-4.32%;
Intengo yemakethe ye-Propylene glycol East China ingu-8900 yuan/ton, ikhuphuke ngo-6.32%;
Intengo yemakethe ye-DMC East China ingu-4600 yuan/ton, ikhuphuke ngo-4.2%;
Intengo yemakethe ye-isopropyl alcohol yaseMpumalanga China ingu-6775 yuan/ton, ikhuphuke ngo-1.1%;
Intengo yemakethe ye-acrylic acid empumalanga yeShayina ingu-6750 yuan/ton, ikhuphuke ngo-4.26%;
Intengo yemakethe ye-butyl acrylate East China ingu-8800 yuan/ton, ikhuphuke ngo-2.22%.
I-emulsion ye-Acrylic
Ngokuphathelene nezinto zokusetshenziswa, imakethe ye-acrylic ingaqhubeka nokuba sengozini ngesonto elizayo; imakethe ye-styrene ingagcina isikhathi; maqondana ne-methamphetamine noma ama-disk abuthakathaka. Ukusebenza kwezindleko okuphelele kokubhekisela kokuzinza okuyisisekelo. Ngokuphathelene nokuhlinzekwa, amadiphozithi okuqala embonini azohlala eqinile futhi athuthukiswe ngesonto elizayo, futhi umkhiqizo ungase ungashintsha kakhulu. Amathuba okuba nempahla ephezulu kwamanye amafektri asekhona. Ngokuphathelene nesidingo, isidingo sokugcina asisihle njengoba bekulindelekile, futhi inani lama-oda angezansi lingase ligcine izinga eliphansi eliphakathi. Kulindeleke ukuthi imakethe ye-acrylic emulsion ingase isaxoxisana ngokubaluleka kokuthunyelwa.
Amanani ezinto zokusetshenziswa eziyinhloko zokumboza ahlukaniswa, amanani e-N-butanol, i-Neopentarglycol, i-Xylene neminye imikhiqizo ekhuphuka, kodwa amanani e-epoxy resin, i-MDI, i-butyl acrylate kanye nemikhiqizo ehlobene nayo ochungechungeni lwemboni aqhubeka nokwehla, futhi ukuthambekela kokwehla kwanda.
I-Neopentyl glycol/Isobutyraldehyde:Imakethe yasekhaya ye-neopentylene glycol iyakhuphuka, intengo yezinto zokusetshenziswa ikhuphuka kancane, ukwesekwa kwezindleko kuyakhuphuka, inkontileka ye-neopentylene glycol yenziwa ngokulandelana okukhulu, indawo iqinile, intengo yemakethe ephansi iya phezulu, kodwa izimboni ze-polyester resin ezingezansi ziyalandela ngokuvamile, isitokwe singaphansi kwengcindezi, futhi ukulandelwa kwemakethe akwanele. Kuze kube manje, imakethe yasekhaya ye-neopentylene glycol ingu-10,500-10,800 yuan/ton. Intengo ye-isobutyral ingu-7600-7700 yuan/ton.
I-butyl acrylate:Ukushaqeka kwemakethe ye-butyl acrylate kwehle, amanani ehla engxenyeni yokuthenga okuphansi kwe-terminal, kodwa ukuthengiselana okukodwa kwangempela kwamanani aphansi. Kuze kube manje, i-yuan engu-8,700-8800/ton emakethe yase-East China, umthwalo wamanje wezimboni ungaphansi kuka-5%. Kodwa ngenxa yokuntuleka kwesidingo, izinguquko eziyisisekelo zemakethe ye-butyl acrylate zinciphile, inani lemakethe yamanje alilikhulu. Muva nje, imakethe ye-acrylic iqhubekile nokushaqeka.
I-Epoxy resin/i-Bisphenol A/ i-Epichlorohydrin:Intengo ye-epoxy resin yasekhaya yaqhubeka nokwehla, intengo ye-epoxy resin e-East China yehle yaya ku-13500-14200 yuan/ton; i-epoxy resin eqinile ye-Huangshan 13400-13900 yuan/ton. Izinto zokusetshenziswa eziphezulu ze-epoxy resin bisphenol A kanye ne-epichlorohydrin zaqhubeka nokwehla ngesonto, futhi ukusekelwa kobuso bezindleko ze-resin kwakubuthakathaka. Abakhiqizi bathumela ngenzuzo ngaphansi kwengcindezi yendawo yokugcina, futhi intshiseko yokuthenga engezansi yayisebuthakathaka. Njengoba intengo yehla iye ezingeni eliphansi, abaqhubi ngokusobala abanalo ithemba emakethe yesikhathi esizayo, amabhizinisi agcina izinto ezithintekayo ekuthengeni ukuze alondoloze inani elincane lesidingo esiqinile, isikhungo samandla adonsela phansi siyabuthaka, kulindeleke ukuthi i-epoxy resin yasekhaya emkhathini ocindezelekile ingase iqhubeke nokwehla. Intengo ye-epoxy resin yase-East China 9450 yuan/ton, intengo ye-epichlorohydrin yase-East China 8500 yuan/ton.
