Chigadzirwa molecular chimiro:
Phthalic anhydride ndiyo organic compound ine formula C6H4(CO)2O.Ndiyo anhydride yephthalic acid.Ichi chisina ruvara chakasimba ikemikari yakakosha yeindasitiri, kunyanya kugadzirwa kwakakura kwemapurasitiki emapurasitiki
.Phthalic anhydride ikemikari yakakosha yepakati muindasitiri yepurasitiki kubva iyo inotorwa akawanda phthalate esters anoshanda seplasticizers mumasynthetic resins.Phthalic anhydride pachayo inoshandiswa semonomer yekugadzira resin senge glyptal, alkyd resins, uye polyester resins.
Phthalic anhydride inoshandiswawo seyakatangira anthraquinone, phthalein, rhodamine, phthalocyanine, fluorescein, uye xanthene dhayi.
Phthalic anhydride inoshandiswa mukugadzirisa kwekutanga amines, yekurima fungicide phaltan, uye thalidomide.Kumwe kuita nephthalic anhydride kunoburitsa phenolphthalein, benzoic acid, phthalylsulfathiazole (intestinal antimicrobial agent), uye orthophthalic acid.
Komboni iyi ikemikari yepamusoro-tonnage uye inoshandiswa zvakanyanya mumhando dzakasiyana dzeindasitiri organic syntheses.
Phthalic anhydride inoshandiswa mukugadzira polyester isina unsaturated uye semushonga wekurapa epoxy resins.Kana yakashandiswa se pigment, inogona kuve nebasa rekukurudzira muvashandi veceramic.
Phthalic Anhydride is organic compound uye anhydride yephthalic acid (P384480).Phthalic Anhydride ikemikari yakakosha yemaindasitiri inowanzoshandiswa mukugadzirwa kwakakura kweplasticizers f kana mapurasitiki.Tsvagiridzo ichangoburwa yakaongororawo Phthalic Anhydride seanogona antibacterial agent.
kugadzirwa kwephthaleins, phthalates, benzoic acid, synthetic indigo, resins yekugadzira (glyptal).
Zvepakati zvePlastizer, Pendi, Dhayi uye Pigment, Polyester Resins.
Chemwin inogona kupa huwandu hwakawanda hwemahydrocarbon akawanda uye makemikari zvinonyungudutsa kune vatengi vemaindasitiri.Izvi zvisati zvaitika, ndapota verenga zvinotevera ruzivo rwekuita bhizinesi nesu:
1. Chengetedzo
Chengetedzo ndiyo inonyanya kukosha kwatiri.Pamusoro pekupa vatengi ruzivo nezve mashandisiro akachengeteka uye ane hushamwari ezvigadzirwa zvedu, isu takazvipirawo kuona kuti njodzi dzekuchengetedza dzevashandi nemakondirakiti dzadzikiswa kuita shoma inonzwisisika uye inogoneka.Naizvozvo, isu tinoda kuti mutengi ave nechokwadi chekuti kurodha kwakakodzera uye kuchengetedza kuchengetedza zviyero zvinosangana tisati tasvitsa (ndapota tarisa kune HSSE appendix muhuwandu hwematemu uye mamiriro ekutengesa pazasi).Nyanzvi dzedu dzeHSSE dzinogona kupa gwara pane aya mazinga.
2. Delivery nzira
Vatengi vanogona kuraira uye kuendesa zvigadzirwa kubva kuchemwin, kana kuti vanogona kugamuchira zvigadzirwa kubva kune yedu kugadzira chirimwa.Nzira dziripo dzekutakura dzinosanganisira rori, njanji kana multimodal kutakura (zvakasiyana mamiriro anoshanda).
Panyaya yezvinodiwa nevatengi, tinogona kutsanangura zvinodikanwa zvemabhaji kana matangi uye kushandisa yakakosha kuchengetedza / kuongorora zviyero uye zvinodiwa.
3. Minimum order yakawanda
Kana iwe ukatenga zvigadzirwa kubva pawebhusaiti yedu, iyo yakaderera odha huwandu i30 matani.
4.Payment
Iyo yakajairika nzira yekubhadhara inobviswa zvakananga mukati memazuva makumi matatu kubva painvoice.
5. Delivery zvinyorwa
Mapepa anotevera anopiwa kune imwe neimwe yekutumira:
· Bill of Lading, CMR Waybill kana rimwe gwaro rekufambisa rakakodzera
· Sitifiketi Yekuongorora kana Conformity (kana zvichidikanwa)
· Zvinyorwa zvine chekuita neHSSE zvinoenderana nemitemo
· Zvinyorwa zvetsika zvinoenderana nemirairo (kana zvichidikanwa)
