CAS nhamba:109-99-9
Chigadzirwa chemolecular chimiro:
Tetrahydrofuran (THF) imvura isina ruvara, inoshanduka ine ethereal kana acetone sechinhuhwira uye inosanganiswa mumvura uye yakawanda organic zvinonyungudutsa. Inopfuta zvakanyanya uye inogona kuora nekushisa kuita kabhoni monoxide necarbon dioxide. Kuchengetedza kwenguva refu mukusangana nemhepo uye kana pasina antioxidant kunogona kukonzera THF kuparara kuita peroxides inoputika.
Tetrahydrofuran inoshandiswa mukugadzira mapolymers pamwe nemishonga yekurima, yemishonga, uye yezvigadzirwa. Zviitiko zvekugadzira zvinowanzoitika mumasisitimu akavharwa kana pasi pehuinjiniya zvinodzora izvo zvinomisa kuratidzwa kwevashandi uye kusunungurwa kune zvakatipoteredza. THF inoshandiswawo sechinhu chinonyungudutsa (semuenzaniso, kupinza pombi) izvo zvinogona kukonzera kuratidzwa kwakanyanya kana kuchishandiswa munzvimbo dzakavharirwa pasina mhepo yakakwana. Kunyangwe hazvo THF ichingowanikwa mukunhuhwirira kwekofi, peas yakakangwa, uye huku yakabikwa, kuratidzwa kwechisikigo hakutarisirwe kuunza njodzi huru.
Butylene oxide inoshandiswa sefumigant uye isina kusanganiswa nemamwe macompound. Inoshandiswa kudzikamisa mafuta nekuremekedza kuumbwa kwemavara uye matope.
Tetrahydrofuran inoshandiswa seyakagadziriswa forresins, vinyls, uye yakakwirira mapolymers; seGrignardreaction medium ye organometallic, uye simbi hydride reactions; uye mune synthesof succinic acid uye butyrolactone.
Tetrahydrofuran inoshandiswa kunyanya (80%) kugadzira polytetramethylene ether glycol, iyo polima yepasi inoshandiswa kunyanya mukugadzirwa kwe elastomeric fibers (eg, spandex) pamwe ne polyurethane uye polyester elastomers (semuenzaniso, yakagadzirwa nematehwe, skateboard mavhiri). Iyo yasara (20%) inoshandiswa mukunyungudutsa zvikumbiro (semuenzaniso, simende dzepombi, zvinonamira, ingi dzekudhinda, uye tepi yemagineti) uye sechinhu chinonyungudutsa mumakemikari nemishonga syntheses.
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)
