Lub luag haujlwm thiab siv Phenol Formaldehyde Resin

Phenol Formaldehyde Resinyog resistant rau qaug zog acids thiab tsis muaj zog bases, decomposes nyob rau hauv muaj zog acids, thiab corrodes nyob rau hauv muaj zog bases. Nws yog insoluble hauv dej, tab sis soluble hauv organic solvents xws li acetone thiab cawv. Nws yog tau los ntawm polycondensation ntawm phenol-formaldehyde los yog nws derivatives.
Kev siv:
1. Feem ntau yog siv rau kev tsim cov dej-resistant plywood, fiberboard, laminated board, tshuab xaws board, rooj tog, thiab lwm yam. Nws kuj tseem siv tau rau kev sib txuas cov ntaub ntawv ntxeem tau xws li iav fiber ntau laminated board thiab foam plastics thiab bonding sand pwm rau casting;
2. Nws muaj cov dej tsis zoo, ruaj khov thiab nws tus kheej lubricating zog, thiab yog siv rau moldings ntawm tus kheej lubricating bearings, roj meter Cheebtsam, thiab dej twj tso kua mis vaj tse impellers;
3. Nws yog siv rau hauv kev lag luam txheej, kev sib tsoo ntoo, kev lag luam foundry, kev lag luam luam ntawv, xim, number case thiab lwm yam lag luam;
4. Nws yog tsuas yog siv los ua cov khoom siv nrog cov hlau ntxig thiab cov khoom siv hluav taws xob siab rau cov khoom siv hluav taws xob, kev ntsuas, kev sib txuas lus, kev lag luam aviation thiab tsheb thiab cov khoom siv hluav taws xob;
5. Siv los tsim cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, thiab lwm yam;
