Mugadziri Mutengo Wakanaka PVB (Polyvinyl Butyral Resin) CAS:63148-65-2

tsananguro pfupi:

Polyvinyl Butyral Resin (PVB) chigadzirwa chinobatwa nepolyvinyl alcohol nebutadhyde pasi peacid catalytic. Nekuti mamorekuru ePVB ane matavi marefu, ane hunyoro hwakanaka, tembiricha yakaderera yegirazi, simba guru rekutambanudza uye simba rinodzivirira kukanganiswa. PVB ine kujeka kwakanaka, inonyunguduka zvakanaka, uye inodzivisa chiedza zvakanaka, inodzivisa mvura, inodzivisa kupisa, inodzivisa kutonhora, uye inoumbwa nefirimu. Ine mapoka anoshanda anogona kuita maitiro akasiyana-siyana akadai seacetylene-based saponification reactions, vinegaring yehydroxyl, uye sulfonic acidization. Ine kunamatira kwakanyanya negirazi, simbi (kunyanya aruminiyamu) nezvimwe zvinhu. Saka, yakashandiswa zvakanyanya muminda yekugadzira magirazi ekuchengetedza, manamati, bepa remaruva eceramic, bepa realuminium foil, zvinhu zvemagetsi, zvigadzirwa zvekusimbisa magirazi, mishonga yekurapa machira, nezvimwewo, uye inova chinhu chakakosha chekugadzira resin.

Mashandisirwo ePVB

1. Firimu rakatetepa rinoshandiswa kugadzira zvinhu zvemasangweji zvegirazi rakachengeteka. Girazi rakachengeteka rakanaka uye rine simba guru rekukanda. Rinoshandiswa zvakanyanya mundege nemotokari.
2. Inoshandiswa kugadzira machira esimbi pasi uye pendi inotonhora ine kunamatira kwakasimba uye inodzivirira mvura ine kunamatira kwakasimba uye inodzivirira mvura.
3. Inoshandiswa kugadzira bepa reruva rakajeka, rinogona kutsiva bepa reruva receramic. Indasitiri yeresin inoshandiswa kugadzira mapurasitiki ekupwanya simbi dzisina ferrous dzakadai sesimbi nelead, dzinogona kuenzaniswa nemarudzi akasiyana-siyana ekunamira. Inoshandiswa zvakanyanya pakubatanidza huni, ceramic, simbi, mapurasitiki, dehwe, uye zvinhu zvinomanikidza.
4. Inoshandiswa kugadzira zvinhu zvinogadzirisa machira uye chubhu ye gauze. Indasitiri yezvekudya inoshandiswa kugadzira zvinhu zvine chepfu pakurongedza.
5. Indasitiri yekugadzira mapepa inoshandiswa kugadzira mishonga yekurapa mapepa. Pamusoro pezvo, inogona kushandiswa kugadzira mishonga inodzivirira kupwanyika, mishonga yakaoma nezvimwe zvinhu zvisingapindi mvura.
6. Inogona kushandiswa kupfava kweindasitiri yekudhinda, kudhinda kwakakombama, kudhinda kwakakombama, kudhinda siriki, kutamisa kupisa, nekuti inonyungudutswa mudoro uye haina chepfu, chisimbiso hachirambe chiri hwema, hunogona kushandiswa muindasitiri yezvekudya inonzwa hwema muindasitiri yezvekudya. Zvakadai setii/fodya. Nekuti resin yacho ine rudzi rwecedic, ine kunamira kwakanaka pamusoro pegirazi ine yin ion yakasimba, iyo inonyanya kukodzera kushongedza magirazi epurasitiki.
