Tsarin kwayoyin halitta:
Polycarbonate(PC) mara launi ne, m, polymer amorphous gilashi tare da kyawawan kaddarorin gani. PC high kwayoyin guduro yana da high tauri, cantilever katako notched tasiri ƙarfi ne 600 ~ 900J/m. Matsayin da ba a cika ba yana da yanayin zafi na murdiya kusan 130 ° C, wanda za'a iya ƙarawa da 10 ° C bayan an ƙarfafa shi da fiber gilashi. Modules mai sassauƙa na PC na iya kaiwa fiye da 2400 MPa, don haka ana iya sarrafa shi cikin babban samfuri mai ƙarfi. A ƙasa da 100 ° C, ƙimar da ke ƙarƙashin kaya yana da ƙasa sosai. PC ba shi da kyau a cikin juriya na hydrolysis kuma ba za a iya amfani da shi akai-akai don aiwatar da abubuwan da aka yiwa tururi mai ƙarfi ba.
Polycarbonates robobi ne da ake amfani da su sosai a masana'antar zamani waɗanda ke da kyakkyawan yanayin zafi da juriya mai tasiri. Wannan filastik yana da kyau musamman don yin aiki tare da ƙarin fasahohin ma'anar na al'ada (na yin gyare-gyaren allura, extrusion cikin tubes ko cylinders da thermoforming). Hakanan ana amfani dashi lokacin da ake buƙatar bayyananniyar gani, yana da watsawa sama da 80% har zuwa kewayon 1560-nm (gajeren kewayon infrared infrared). Yana da matsakaicin kaddarorin juriya na sinadarai, kasancewa mai juriya da sinadarai ga diluted acid da alcohols. Ba shi da ƙarancin juriya ga ketones, halogens, da acid mai tattarawa. Babban rashin lahani da ke da alaƙa da polycarbonates shine ƙananan zafin canjin gilashin (Tg> 40 ° C), amma har yanzu ana amfani da shi azaman ƙarancin farashi a cikin tsarin microfluidic kuma har ma a matsayin Layer na hadaya.
Chemwin na iya samar da nau'ikan nau'ikan hydrocarbons da abubuwan kaushi na sinadarai don abokan cinikin masana'antu.Kafin wannan, da fatan za a karanta mahimman bayanai masu zuwa game da yin kasuwanci tare da mu:
1. Tsaro
Tsaro shine babban fifikonmu. Baya ga samar wa abokan ciniki bayanai game da aminci da amincin amfani da samfuran mu, mun kuma jajirce wajen tabbatar da cewa an rage haɗarin aminci na ma'aikata da 'yan kwangila zuwa mafi ƙanƙanta mai yuwuwa. Sabili da haka, muna buƙatar abokin ciniki don tabbatar da cewa an cika daidaitattun ƙa'idodin saukarwa da aminci na ajiya kafin isar da mu (da fatan za a koma zuwa ƙarin bayanin HSSE a cikin sharuɗɗan tallace-tallace na gaba ɗaya da ke ƙasa). Kwararrun mu na HSSE na iya ba da jagora akan waɗannan ƙa'idodi.
2. Hanyar bayarwa
Abokan ciniki na iya yin oda da isar da kayayyaki daga chemwin, ko kuma za su iya karɓar samfuran daga masana'antar masana'anta. Hanyoyin sufurin da ake da su sun haɗa da manyan motoci, jirgin ƙasa ko jigilar kayayyaki da yawa (sharuɗɗan daban sun shafi).
Game da buƙatun abokin ciniki, za mu iya ƙididdige buƙatun jiragen ruwa ko tankuna da amfani da ƙa'idodin aminci / bita na musamman da buƙatu.
3. Mafi ƙarancin tsari
Idan ka sayi samfura daga gidan yanar gizon mu, mafi ƙarancin tsari shine ton 30.
4.Biyan kuɗi
Daidaitaccen hanyar biyan kuɗi shine cirewa kai tsaye a cikin kwanaki 30 daga daftari.
5. Takardun bayarwa
Ana ba da waɗannan takaddun tare da kowace bayarwa:
Bill of Lading, CMR Waybill ko wasu takaddun jigilar kayayyaki masu dacewa
Takaddun Takaddun Bincike ko Daidaitawa (idan an buƙata)
