Xabag-ku-saleysan TPU-da koollada oo wanaagsan
ku saabsan TPU
TPU (polyurethane heerkulbeeg ah) ayaa isku xidha farqiga walxaha u dhexeeya caagadaha iyo caagadaha. Noocyada kala duwan ee hantida jireed waxay awood u siinaysaa TPU in loo isticmaalo labadaba caag adag iyo thermoplastic injineer jilicsan.TPU waxay ku guulaysteen isticmaalka baahsan iyo caannimada kumanaan alaab ah, taas oo ay ugu wacan tahay cimrigooda, jilicsanaantooda iyo midabaynta faa'iidooyinka kale. Intaa waxaa dheer, way fududahay in la farsameeyo.
Iyada oo ah qalab tikniyoolajiyadeed sare leh oo soo baxaya iyo agab deegaan-saaxiibtinimo ah, TPU waxay leedahay sifooyin aad u fiican sida kala duwanaansho adag oo ballaadhan, xoog farsamo oo sarreeya, iska caabin qabow oo heersare ah, wax qabad wanaagsan oo wax-qabad, nabaad-guur ku habboon deegaanka, iska caabbinta saliidda, caabbinta biyaha iyo caabbinta caaryada.

Xidhmada
25KG/bac, 1000KG/pallet ama 1500KG/pallet, balaastig la warshadeeyay
Wax ka qabashada iyo Kaydinta
1. Iska ilaali in aad neefsato qiiqa habaynta kulaylka iyo uumiga
2. Qalabka farsamada gacanta ayaa sababi kara samaynta boodh. Iska ilaali siigada neefsashada.
3. Isticmaal farsamooyinka dhulka hoostiisa saxda ah marka aad alaabtan gacanta ku hayso si aad uga fogaato kharashaadka korontada
4. Pellets dhulka waxa laga yaabaa inay simbiriirixanayaan oo ay sababaan inay dhacaan
Talooyinka kaydinta: Si loo ilaaliyo tayada alaabta, ku kaydi alaabta meel qabow oo qalalan. Ku hay weel si adag u xiran.
Xusuusin
1. Walxaha TPU xumaaday looma isticmaali karo in lagu farsameeyo alaabta.
2. Ka hor inta aan la dhejin, waxaa lagama maarmaan ah in si buuxda loo qalajiyo, gaar ahaan inta lagu jiro naqshadeynta extrusion, dharbaaxada, iyo filimaanta afuufista, oo leh shuruudo adag oo loogu talagalay qoyaanka, gaar ahaan xilliyada qoyan iyo meelaha qoyaanka badan.
3. Inta lagu jiro wax-soo-saarka, qaab-dhismeedka, saamiga isku-buufinta, qoto-dheeraanta, iyo saamiga L / D ee muraayadda waa in la tixgeliyaa iyadoo lagu saleynayo sifooyinka walxaha. Naqshadeeyaha cirbadeynta waxaa loo isticmaalaa qaabeynta cirbadeynta, iyo furayaasha extrusion waxaa loo isticmaalaa extrusion.
4. Iyada oo ku saleysan dareeraha walxaha, tixgeli qaab dhismeedka caaryada, cabbirka gudaha xabagta, cabbirka sanka, qaabka qulqulka qulqulka, iyo booska dekedda qiiqa.
