Chii chinonzi LFT mold uye chii mutsauko neSMC mold

1. Nhanganyaya kuLFT
LFT, refu fiber yakasimbisa thermoplastic zvinhu, Chirungu ndeye Long Fiber yakasimbiswa Thermoplastics, inofananidzwa neyakajairwa fiber yakasimbiswa thermoplastic zvinhu, kazhinji, iyo fiber kureba yefiber yakasimbiswa thermoplastic zvinhu isingasviki 1 mm, nepo LFT, Kureba kwefiber kunowanzo. yakakura kupfuura 2 mm. Ikozvino yekugadzira tekinoroji yakakwanisa kuchengetedza urefu hwefiber muLFT pamusoro pe5 mm.
2. LFT kuumbwa
LFT (Long Glass Fiber Reinforced Plastic) ongororo yakavakirwa pamicro-spectrum yekuongorora tekinoroji, iyo inoongorora zviri mukati mechikamu chega chega chezvinyorwa zvakadhindwa kuburikidza nemicro-spectrum uye kudzoreredza fomula yekutanga. Yakareba fiber-yakasimbiswa thermoplastic zvinhu inofananidzwa neyakajairika fiber-yakasimbiswa thermoplastic zvinhu. Iyo inonyanya kushandiswa matrix resin iPP, inoteverwa nePA, uye mamwe marenzi akadai sePBT, PPS, uye SAN anoshandiswawo. LFT ine akawanda maapplication mumotokari, uye mukana mukuru ndeyekuchinjika umo izvo zvinhu zvinogona kusanganiswa.
Chechitatu, musiyano uripo pakati peLFT neSMC
Iyo yekugadzira chigadzirwa maitiro eLFT pepa yakafanana zvakanyanya neSMC (Sheet Molding) mune thermosetting composite girazi fiber yakasimbiswa mapurasitiki. Inogadzirwawo nekutsikirira mapepa muforoma. LFT ishepa rakaoma iro rinopisa uye rakapfava uyezve kutonhora-kudzvanywa mu mold, nepo SMC ichipisa-yakadzvanywa mushure mekutonhora nyoro pepa yakaiswa mu mold.
Kuenzaniswa neSMC sheet, iyo tekinoroji yeLFT sheet ine zvinotevera zvakanakira:
1. Hazvikuvadzi uye zvisingaravi, zvinogona kuvandudza nzvimbo yekushanda.
2. Chiedza chechiedza, density inongova 1 ~ 1.2g / cm3.
3. Zvimedu nemarara zvinogona kushandiswa zvakare kuderedza marara.
4. Simba rakakwirira kudarika SMC, uye kuoma kwemaitiro kunonyanya kukosha.
5. Corrosion resistance uye kushanda kwemagetsi zviri nani.
6. Chigadzirwa chekutsikirira kumhanya chakapetwa kakati wandei kupfuura SMC, uye kugona kwekugadzira kunovandudzwa zvakanyanya.
