I-PP vs. Izixhobo ze-Pes kwi-Orthodontic Braces

I-PP (i-polypropylene) kunye ne-Polythylene) zimbini iiplasitiki eziqheleke ngokwahluka kweekhemikhali, iipropathi zomzimba, ukuxhathisa ubushushu, kunye noluhlu lwezicelo:

Ubume bekhemikhali : Icandelo eliphambili le-PP yiPolypropylene, ngelixa icandelo eliphambili le-PEALTHLETHINE.

Iipropathi zomzimba: I-PP idla ngokufumana indawo ephezulu yokunyibilikisa kunye nobushushu obune-PEL kune-PE, ukuze ikwazi ukujamelana nobushushu obuphakathi: Ukuxinana kwe-PE kuhlala kuluhlu lwe-PP kuluhlu lwe-PP kuluhlu lwe I-0.90 ~ 0.91G / CM³, kunye nobunzima kunye nokungqongqo kwe-PP kudla ngokuba ngaphezulu kwe-PE, kodwa ubunzima buhlwempuzekile kumaqondo obushushu asezantsi.

Ukuxhathisa ubushushu: I-Pe inobushushu obunobushushu obuphantsi, inokusetyenziswa ngokuqhelekileyo kwindawo ye-60 ℃, kodwa iqondo lobushushu lingaphezulu lama-90 degrees celsius. Ukuchasana nobushushu obuphezulu se-PP kungcono kakhulu, kunokusetyenziswa ngokuqhelekileyo kwi-100 degrees Celsius, kwaye kungafuduswa kwi-oveni ye-microwave.

Ubungakanani besicelo:

I-PE iqhele ukusetyenziswa ekwenzeni iifilimu, izikhongozeli, imibhobho, i-inshule kunye nezinye iimveliso ezifuna ukuba bhetyebhetye kunye nokunganyangeki kubandayo. Kwaye i-PP iqhele ukusetyenziswa ekwenzeni imibhobho, i-sond yangasese, izixhobo zasekhaya, iplastiki, umzi-mveliso we-tubsing kunye nozinzo oluphezulu.

Ukuguquguquka: I-PE STOUST ithambile, kulula kakhulu ukuba ichaphazele emva kokuba inyibilikisiwe; Ngelixa izinto ze-PP zilukhuni kakhulu, ziguqulwe kancinci.

Ukuxhathisa kwemozulu: I-PE inamamela okuphezulu kwemozulu, ngelixa i-PP ine-POOTE yemozulu.

UKHUSELEKO: I-PE kunye ne-PP ayinatyhefu, izinzile ngamachiza kwaye kulula ukubumba kunye nenkqubo.

Ngokubanzi, i-PP kunye ne-PE kunye neenzuzo zabo ngokwendlela yokusebenza, kwaye ukhetho lwento oza kuyisebenzisa ixhomekeke kwiimfuno ezithile zesicelo.

Sikunika ukuthelekisa namhlanje umahluko phakathi kwe-PP kunye ne-PET isetyenziswe ngokubanzi kwi-orthotiki.

I-PE yile nto sihlala sibhekisa kwi-polythylene.looks kufutshane nomhlophe ococekileyo;

I-PP yiPolypropylene, ezi zinto zimbini zithelekiswa nezinto eziluncedo kunye nezinto eziluncedo kuyo, uninzi lwezinto ezibalaseleyo kukuba amandla e-berm iphakame kakhulu kune-PE, oko kukuthi maxesha amathuba e Isixhobo se-PP akukho lula ukuphelisa, kunye namandla e-PP kwaye amandla omxholo womelele ngakumbi, ngokusekwe kwiimpawu zezinto ezibonakalayo, ukukhetha izinto zePP, inkxaso inokwenziwa ukuyenza ilula kwaye incinci.

Xa kuthelekiswa ne-PE, iintsilelo zezinto ze-PP yiqondo lobushushu lwe-PP liphezulu, kubangela ukuba amandla alo eyokuqhushumba anzima kune-PE, ekufumaneni impembelelo yempembelelo enkulu, okanye iqhekeza, thina Kukukhethwa kwezinto zenkxaso, kufuneka simamele ingcebiso yokuyisela inkxaso yokukhetha eyona nto ifanelekileyo.
