Phthalic anhydride
Phthalic anhydride ndi organic pawiri ndi chilinganizo C6H4(CO)2O. Ndi anhydride wa phthalic acid. Cholimba chopanda mtunduchi ndi chinthu chofunikira kwambiri m'mafakitale, makamaka pakupanga kwakukulu kwa mapulasitiki apulasitiki.
Phthalic anhydride ndi mankhwala ofunikira apakati pamakampani opanga mapulasitiki omwe amachokerako ma esters angapo a phthalate omwe amagwira ntchito ngati mapulasitiki mu utomoni wopangira. Phthalic anhydride palokha imagwiritsidwa ntchito ngati monomer pakupanga utomoni monga
glyptal, alkyd resins, ndi polyester resins.

mfundo:

Pakali pano, phthalic anhydride amagwiritsidwa ntchito kwambiri m'makampani opanga mankhwala, mankhwala, zamagetsi, ulimi, utoto, mafakitale abwino a mankhwala ndi mafakitale ena.
China benzene anhydride zimagwiritsa ntchito kupanga phthalic acid lipids plasticizer, wabwino benzene anhydride nkhani pafupifupi 60% ya okwana kumwa benzene anhydride, utoto ndi utoto nkhani 25%, unsaturated utomoni ndi zinthu zina nkhani pafupifupi 15%.
Phenylanhydride ndi yofunika organic mankhwala zopangira, makamaka ntchito kupanga plasticizers pulasitiki, alkyd utomoni, utoto, unsaturated resins ndi mankhwala ena ndi mankhwala.

Weifang JS Chemical Co., Ltd. ndi kampani yapadziko lonse yogulitsa mankhwala ndi kupanga yomwe ili ku WEIFANG CITY, CHINA.
Ndi mfundo ya malonda oona mtima ndi kupambana-kupambana, utumiki wapamwamba ndi chitukuko chokhazikika. Takhazikitsa nthawi yayitali
ndi ubale wokhazikika wamabizinesi ndi mabizinesi ambiri otchuka amankhwala kunyumba ndi kunja, ndipo adapeza chithandizo chachikulu ndi chidaliro kuchokera kwa makasitomala athu.
Fakitale yathu yathunthu ili ku Binhai Economic-Technological Development Area (dera lachitukuko chazachuma ndi ukadaulo) ku Weifang.
 Pakalipano, fakitale ili ndi chomera cha 2-ethylanthraquinone cha matani 3000 / chaka chokhala ndi ufulu wodziyimira pawokha waumwini, womwe wafika pamlingo wapamwamba waukadaulo ku China. Kuphatikiza apo,
 imakhala ndi zomera zothandizira, monga chomera cha anhydrous aluminium trichloride cha matani 2,500 / chaka, chomera cha polyaluminium chloride cha matani 20, 000 / chaka, chomera cha magnesium sulfate cha matani 100, 000 / chaka,
potassium sulphate chomera cha matani 60, 000/chaka ndi sulfuric acid chomera matani 60, 000/chaka. Ili ndi akatswiri a R&D ndi luso lakapangidwe, luso lapamwamba lopanga komanso njira yabwino yochitira pambuyo pogulitsa.
Weifang JS Chemical Co., Ltd nthawi zonse imatsatira nzeru za opareshoni ya "Lolani Ogwira Ntchito Asangalale, Alole Makasitomala Apambane, Athandizeni ku Sosaiti", ndipo amapereka makasitomala ntchito zapamwamba kwambiri pogwiritsa ntchito njira zokhazikika komanso zokhazikika.
zinthu zapamwamba zotsika mtengo komanso upangiri wamagulu a akatswiri apamwamba.

Q1: Kodi mudzabereka liti?
A: tidzakuberekerani pasanathe masiku 15 ogwira ntchito mutalandira kulipira kwanu.
Q2: Kodi ndiyenera kulipira motani?
A: Timalola mitundu yonse yamalipiro. monga Alibaba malonda Chitsimikizo, T / T, L / C, West mgwirizano, Paypal etc.
Q3: Ndingapeze bwanji chitsanzo?
Yankho: Zitsanzo zaulere zilipo, koma zolipiritsa zonyamula katundu zizikhala pa akaunti yanu ndipo zolipiritsa zidzabwezedwa kwa inu kapena kuchotsedwa ku oda yanu mtsogolomo.
Q4: Kodi mungatsimikizire bwanji Zamalonda musanayike maoda?
A: Mutha kupeza zitsanzo zaulere pazinthu zina, mumangofunika kulipira mtengo wotumizira kapena kukonza zotumiza kwa ife ndikutenga zitsanzo. Mutha kutitumizira zolemba zanu ndi zopempha zanu, tidzapanga zinthuzo malinga ndi zomwe mukufuna.
