Waa maxay faraqa u dhexeeya shandad PP iyo shandad PC?

1. Qalab kala duwan

Shandada PP waa resin polypropylene
Maadaama PP homopolymer uu aad u jajaban yahay heerkul ka sarreeya 0C, alaabooyin badan oo PP ganacsi ah ayaa ah copolymers random oo 1 ilaa 4% ethylene lagu daray ama lagu qooyay kopolymers-ka leh maaddooyinka ethylene sare.
PC-ga shandad ku jira waa aka "polycarbonate".Polycarbonate waa resin thermoplastic adag oo loogu magac daray kooxda CO3 ee gudaha.By bisphenol A iyo kaarboon oxychloride synthesis.Habka ugu badan ee la isticmaalo waa habka transesterification dhalaalay (bisphenol A iyo diphenyl carbonate waxaa lagu farsameeyay transesterification iyo polycondensation).

2. Sifooyin kala duwan

Shandad PP: Nooca copolymer-ka PP wuxuu leeyahay heerkul hoose oo qalloocan (100C), daah-furnaan hoose, dhalaal hooseeya, qallafsanaan hooseeya, laakiin waxay leedahay awood saameyn xooggan.Awoodda PP waxay kordhisaa iyada oo la kordhinayo maadada ethylene.
Heerkulka jilicsan ee Vicat ee PP waa 150C.Sababtoo ah heerka sare ee crystallinity, maaddadani waxay leedahay qallafsanaan dusha sare ah iyo sifooyinka caabbinta xoqan.
Shandada PC: Waa resin thermoplastic amorphous leh oo leh sifooyin dhammaystiran oo heersare ah, oo leh dahaarka korantada oo aad u fiican, dhererka, xasilloonida cabbirka iyo caabbinta kiimikada, xoogga sare, caabbinta kulaylka iyo caabbinta qabow;waxa kale oo uu leeyahay is-daminta, ololka retardant, aan sun ahayn, midab leh, iwm.

3. Xoog kala duwan

Shandad PP: waxay leeyihiin awood saamayn xoog leh.Qalafsanaanta dusha sare iyo sifooyinka caabbinta xoqan ee maaddadan ayaa aad u fiican.
Shandad PC: Xooggeedu waxa uu dabooli karaa baahiyo kala duwan min teleefannada gacanta ilaa muraayadda aanay xabbadu karin.Marka la barbardhigo birta, qallafsanaantiisu kuma filna, taas oo ka dhigaysa muuqaalkeeda si fudud in la xoqo, laakiin xooggeeda iyo adayggeeda ayaa aad u wanaagsan, haddii ay tahay cadaadis culus ama mid guud , ilaa iyo inta aanad isku dayin inaad ruxdo, way kugu filan tahay.
