Guryaha
Iftiiminta indhaha OB waa nooc ka mid ah isku dhafka benzoxazole, waa ur aan lahayn, way adagtahay in lagu milmo biyaha, ku milma paraffin, dufan, saliid macdan ah, dhux iyo dareerayaal dabiici ah oo caadi ah.Waxaa loo isticmaali karaa in lagu caddeeyo balaastikada thermoplastic, PVC, PS, PE, PP, ABS, Acetate fiber, rinjiga, dahaarka, daabacaadda daabacaadda, iwm. Waxaa lagu dari karaa marxalad kasta oo geeddi-socodka caddeynta polymers-ka iyo samaynta alaabta la dhammeeyey. sii daaya dhalaal cad oo buluug ah oo dhalaalaya.
Codsiga
Iftiiminta indhaha OB waa mid ka mid ah iftiimiyeyaasha ugu fiican ee si weyn loogu isticmaalo balaastikada iyo fiilooyinka waxayna leedahay saameyn la mid ah tinopal OB.Waxaa loo isticmaali karaa in thermoplastics, polyvinyl chloride, polystyrene, polyetylen, polypropylene, ABS, acetate, iyo waxa kale oo loo isticmaali karaa varnishes, rinji, dhaldhalaalka cad, dahaarka, iyo khadadka.Waxa kale oo uu leeyahay saamayn aad u wanaagsan oo lagu caddeeyo fiilooyinka synthetic. .Waxay leedahay faa'iidooyinka caabbinta kulaylka, caabbinta cimilada, huruud la'aanta, iyo midabka midabka wanaagsan.Waxaa lagu dari karaa monomer ama walxaha prepolymerized ka hor ama inta lagu jiro polymerization, uumi, polymerization dheeraad ah, ama lagu daro qaabka budada ama pellets. (ie masterbatch) ka hor ama inta lagu jiro samaynta balaastikada iyo fiilooyinka synthetic.
Isticmaalka tixraaca:
1 PVC:
Wixii PVC jilicsan ama adag:
Cadaynta: 0.01 -0.05% (10 - 50g/100KG walxo)
Daah-furnaan: 0.0001 -0.001% (0.1g -1g/100kg walxo)
2 PS:
Cadaynta: 0.001% (1g/100kg walxo)
Daahfurnaanta: 0.0001 -0.001 (0.1 -1g/100kg walxo)
3 ABS:
Ku darida 0.01-0.05% ee ABS waxay si wax ku ool ah u baabi'in kartaa midabka jaalaha ah ee asalka ah waxayna gaari kartaa saameyn cadcad oo wanaagsan.
4 Polyolefin:
Saamaynta nadiifinta wanaagsan ee polyetylen iyo polypropylene:
Daahfurnaan: 0.0005 -0.001% (0.5 -1g/100kg walxo)
Cadaynta: 0.005 -0.05% (5 - 50g/100kg walxo)
Xidhmada
25kg fiber durbaan, oo leh bacda PE gudaha ama codsiga macmiilka.
