Menene LFT mold kuma menene bambanci tare da ƙirar SMC

1. Gabatarwa zuwa LFT
LFT, dogon fiber ƙarfafa thermoplastic abu, Turanci ne Dogon Fiber ƙarfafa Thermoplastics, idan aka kwatanta da talakawa fiber ƙarfafa thermoplastic abu, yawanci, da fiber tsawon fiber ƙarfafa thermoplastic abu ne kasa da 1 mm, yayin da LFT, Tsawon fiber ne kullum. fiye da 2 mm. Fasahar sarrafawa na yanzu ta sami damar kiyaye tsayin fiber a cikin LFT sama da 5 mm.
2. LFT abun da ke ciki
LFT (Long Glass Fiber Reinforced Plastics) bincike ya dogara ne akan fasahar bincike na micro-spectrum, wanda ke nazarin abubuwan da ke cikin kowane bangare na kayan da aka bayyana ta hanyar micro-spectrum kuma ya mayar da tsarin asali. Dogayen kayan aikin thermoplastic na fiber-ƙarfafa ana kwatanta su da kayan aikin thermoplastic na yau da kullun na fiber. Resin matrix da aka fi amfani dashi shine PP, sannan PA, sannan ana amfani da wasu resin irin su PBT, PPS, da SAN. LFT yana da aikace-aikace da yawa a cikin motoci, kuma babban fa'ida shine sassauci wanda za'a iya haɗa kayan.
Na uku, bambanci tsakanin LFT da SMC
Tsarin masana'anta na takaddar LFT yana kama da SMC (Sheet Molding) a cikin filaye mai ƙarfi na gilashin zafin jiki mai ƙarfi. Hakanan ana yin ta ta danna zanen gado a cikin mold. LFT takarda ne mai wuya wanda aka yi zafi da laushi sannan kuma a yi sanyi a cikin mold, yayin da SMC yana da zafi mai zafi bayan an sanya takarda mai laushi mai sanyi a cikin mold.
Idan aka kwatanta da takardar SMC, aikin fasaha na takardar LFT yana da fa'idodi masu zuwa:
1. Mara lahani da m, na iya inganta yanayin aiki.
2. Hasken nauyi, yawa shine kawai 1 ~ 1.2g / cm3.
3. Za a iya sake amfani da tarkace da kayan sharar don rage sharar gida.
4. Ƙarfin yana da girma fiye da SMC, kuma tasirin tasiri yana da fice musamman.
5. Juriya na lalata da mafi kyawun aikin lantarki.
6. Saurin matsawa samfurin yana da sauri sau da yawa fiye da SMC, kuma an inganta ingantaccen aikin samarwa.
