Codsiyada
(ningbo) Taiwan Formosa Plastics pp5090t isticmaalka ugu muhiimsan:
PP waa walxo semi crystalline ah.Way ka adag tahay PE waxayna leedahay meel dhalaalaysa oo sare.Maadaama nooca homopolymer-ka PP uu aad u jajaban yahay marka heerkulku ka hooseeyo 0 ℃, alaabooyin badan oo PP ganacsi ah ayaa ah copolymers random oo leh 1-4% ethylene ama nooca clamp copolymers oo leh maaddo ethylene sare leh.Nooca copolymer-ka PP waxa uu leeyahay heer kulka qallooca hoose (100 ℃), daah-furnaan hoose, dhalaal yar iyo qallafsanaan hoose, laakiin waxa uu leeyahay awood saamayn xoog leh.
Heerka socodka MFR ee PP wuxuu u dhexeeyaa 1 ilaa 40. PP oo leh MFR hooseeya waxay leedahay iska caabin saameyn wanaagsan leh laakiin hoos u dhigida xoogga xajinta.Alaabta leh MFR isku mid ah, xoogga nooca kobolymerka ayaa ka sarreeya kan nooca homopolymer-ka.Sababo la xiriira crystallization, heerka dhimista ee PP waa mid aad u sarreeya, guud ahaan 1.8-2.5%.Labbiska jihaynta ee dhimista ayaa aad uga wanaagsan kan PE-HD iyo agabka kale.Ku darista 30% wax lagu daro galaas waxay yarayn kartaa hoos u dhaca ilaa 0.7%.
Nooca Homopolymer iyo nooca copolymer PP waxay leeyihiin caabbinta nuugista qoyaanka oo aad u fiican, caabbinta daxalka aashitada-saldhigga iyo iska caabinta kala dirida.Si kastaba ha ahaatee, ma laha wax iska caabin ah hydrocarbon udgoon (sida benzene) dareere iyo chlorinated hydrocarbon (kaarbon tetrachloride).PP ma laha iska caabin oksaydh ah heerkulka sare sida PE.
Marka loo eego waxqabadka kore, PP waxay ku habboon tahay alaabooyinka soo socda:
1. Duritaan: valves, accessories, crates, baabuurta, xidhitaanka, qalabka korontada, dhalooyinka biyaha, weelasha cuntada, alaabta guriga, alaabta lagu ciyaaro, irbado aan horay loo buuxin.
2. Extrusion: xaashi qaro weyn, xaashi, tuubo, caws, cajalad xidhidh, xaashida waraaqaha, BOPP film Sheet iyo strip.
3. Wax-qabashada: dhalada.
4. Thermoforming: saxaarad, baaquli, koob jelly, koob biyo ah.
5. dun fidsan: bac tolan, bac weel, rooga.
