Phenol-formaldehyde resin imakonzedwa motere:
C6H5OH+H2C=O —> [-C6H2(OH)CH2-]n
One-Stage Resins. Chiŵerengero cha formaldehyde ndi phenol ndi chokwanira kuti chiwongolero cha thermosetting chichitike popanda kuwonjezera magwero ena ogwirizanitsa.
Magawo Awiri Resins. Chiyerekezo cha formaldehyde ndi phenol ndi chochepa kwambiri kuti chitetezeke kuti thermosetting ichitike popanga utomoni. Panthawiyi utomoniwo umatchedwa novolac resin. Pambuyo pake, hexamethylenetetramine imaphatikizidwa muzinthu kuti ikhale ngati gwero la mankhwala ophatikizirapo panthawi yopangira (ndi kutembenuzidwa ku thermoset kapena kuchiritsidwa).
Phenolic resins amagwiritsidwa ntchito pazigawo zotsika mtengo zomwe zimafuna zabwino zotchingira magetsi, kukana kutentha, kapena kukana mankhwala. Avereji ya alumali ya utomoni umenewu ndi pafupifupi mwezi umodzi pa 21.1°C. Izi zitha kukulitsidwa pozisunga mufiriji pa 1.6 mpaka 10°C. Kusiyanitsa chothandizira (malinga ndi makulidwe ake) ndikukweza kutentha kwa machiritso kufika pa 93 ° C kudzasintha nthawi yochizira kuyambira maola 8 mpaka 15 min.
Kuchepa kwina kumachitika pomaliza kuponya (0.012 mpaka 0.6 mm/mm), kutengera kuchuluka kwa zodzaza, kuchuluka kwa chothandizira, komanso machiritso. Kuchiritsa kwachangu kumabweretsa kuchepa kwakukulu. Popeza machiritso amatha kufulumizitsa, ma phenolics amagwiritsidwa ntchito pochita ntchito zazifupi.
Zigawo zotayira za phenolic zimachotsedwa mosavuta mu nkhungu ngati zotsatsira zomwe zimalimbikitsidwa ndi ogulitsa zikugwiritsidwa ntchito. Posteuring imawongolera zinthu zoyambira pakuponya komalizidwa.
Chemwin ikhoza kupereka ma hydrocarbon ambiri ambiri ndi zosungunulira zamankhwala kwa makasitomala aku mafakitale.Izi zisanachitike, chonde werengani mfundo zotsatirazi zokhuza kuchita bizinesi nafe:
1. Chitetezo
Chitetezo ndicho chofunikira kwambiri chathu. Kuphatikiza pa kupatsa makasitomala chidziwitso chokhudza kugwiritsa ntchito bwino komanso kusamala zachilengedwe kwa zinthu zathu, tadziperekanso kuwonetsetsa kuti chiwopsezo chachitetezo cha ogwira ntchito ndi makontrakitala chikuchepetsedwa kukhala chocheperako komanso chotheka. Choncho, tikufuna kuti kasitomala awonetsetse kuti miyezo yoyenera yotsitsa ndi kusunga chitetezo ikukwaniritsidwa tisanaperekedwe (chonde onani zowonjezera za HSSE pazogulitsa zomwe zili pansipa). Akatswiri athu a HSSE atha kupereka chitsogozo pamiyezo iyi.
2. Njira yobweretsera
Makasitomala amatha kuyitanitsa ndikutumiza zinthu kuchokera ku chemwin, kapena atha kulandira zinthu kuchokera kumakampani athu opanga. Njira zoyendera zomwe zilipo zikuphatikiza magalimoto, njanji kapena ma multimodal (mikhalidwe yosiyana imagwira ntchito).
Pankhani ya zofuna za makasitomala, titha kufotokoza zofunikira za mabwato kapena akasinja ndikugwiritsa ntchito miyezo yapadera yachitetezo / kuwunika ndi zofunikira.
3. Kuchuluka kwa dongosolo lochepa
Ngati mumagula zinthu patsamba lathu, kuchuluka kwa madongosolo ocheperako ndi matani 30.
4.Kulipira
Njira yolipirira yokhazikika imachotsedwa mwachindunji mkati mwa masiku 30 kuchokera pa invoice.
5. Zolemba zotumizira
Malemba otsatirawa amaperekedwa pakubweretsa kulikonse:
· Bill of Lading, CMR Waybill kapena chikalata china chamayendedwe
· Satifiketi Yowunikira kapena Yogwirizana (ngati pakufunika)
· Zolemba zokhudzana ndi HSSE mogwirizana ndi malamulo
· Zolemba za kasitomu mogwirizana ndi malamulo (ngati pakufunika)
