Yintoni ukungunda kwe-LFT kwaye yintoni umahluko kunye nokubumba kwe-SMC

1. Intshayelelo yeLFT
I-LFT, i-fiber ende eyomeleziweyo yezinto ze-thermoplastic, isiNgesi yi-Long Fiber eyomeleziweyo ye-Thermoplastics, ithelekiswa ne-fiber eqhelekileyo eyomeleziweyo ye-thermoplastic impahla, ngokuqhelekileyo, ubude be-fiber ye-fiber ye-thermoplastic ye-thermoplastic ingaphantsi kwe-1 mm, ngelixa i-LFT, Ubude be-fiber ngokubanzi. ngaphezulu kwe-2 mm. Iteknoloji yokucubungula yangoku iye yakwazi ukugcina ubude befiber kwi-LFT ngaphezu kwe-5 mm.
2. Ukuqulunqwa kwe-LFT
I-LFT (i-Long Glass Fiber Reinforced Plastic) uhlalutyo lusekelwe kwi-teknoloji yohlalutyo lwe-micro-spectrum, ehlalutya umxholo wecandelo ngalinye lezinto ezifakwe kwiprofayili ngokusebenzisa i-micro-spectrum kunye nokubuyisela ifomula esisiseko. Ifiber ende eyomelezwe izixhobo ze-thermoplastic zithelekiswa nezixhobo eziqhelekileyo ze-thermoplastic zefayibha. Eyona resin ye matrix esetyenziswa kakhulu yi PP, ilandelwa yi PA, kunye nezinye iintlaka ezinjenge PBT, PPS, kunye ne SAN nazo ziyasetyenziswa. I-LFT inezicelo ezininzi kwiimoto, kwaye inzuzo ephambili kukuguquguquka apho izinto ezinokudityaniswa.
Okwesithathu, umahluko phakathi kweLFT kunye ne-SMC
Inkqubo yokwenziwa kwemveliso yephepha le-LFT ifana kakhulu ne-SMC (i-Sheet Molding) kwi-thermosetting composite glass fibers ifayibha eqinisiweyo. Kwakhona kwenziwa ngokucinezela amaphepha kwi-mold. I-LFT ishidi elilukhuni elitshisayo kwaye lithambile kwaye emva koko licinezelwe kwi-mold, ngelixa i-SMC ishushu-icinezele emva kokuba ishidi elithambileyo elibandayo lifakwe kwi-mold.
Xa kuthelekiswa nephepha le-SMC, ukusebenza kobugcisa bephepha le-LFT kunezi nzuzo zilandelayo:
1. Ayinabungozi kwaye ayinancasa, inokuphucula indawo yokusebenza.
2. Ubunzima bokukhanya, ubuninzi buyi-1 ~ 1.2g / cm3 kuphela.
3. Izinto ezilahliweyo kunye neemveliso ezilahlwayo zinokuphinda zisetyenziswe ukuze kuncitshiswe inkunkuma.
4. Amandla aphezulu kune-SMC, kwaye ukuqina kwempembelelo kubalaseleyo.
5. Ukumelana nokubola kunye nokusebenza kakuhle kombane.
6. Isantya soxinzelelo lwemveliso siphindaphindeka ngokukhawuleza kune-SMC, kwaye ukusebenza kakuhle kwemveliso kuphuculwe kakhulu.
