Usetyenziso
(ningbo) Taiwan Formosa Plastics pp5090t eyona usetyenziso olungundoqo:
I-PP yimathiriyeli ye-semicrystalline.Inzima kune-PE kwaye inendawo ephezulu yokunyibilika.Ekubeni i-homopolymer uhlobo lwe-PP luba brittle kakhulu xa ubushushu bungaphantsi kwe-0 ℃, izixhobo ezininzi ze-PP zorhwebo zi-copolymers ezingahleliwe kunye ne-1-4% ye-ethylene okanye i-clamp type copolymers enomxholo ophezulu we-ethylene.Uhlobo lwe-PP lwe-copolymer lunobushushu obuphantsi bokuphazamiseka kwe-thermal (100 ℃), ukukhanya okuphantsi, i-gloss ephantsi kunye nokuqina okuphantsi, kodwa unamandla amakhulu empembelelo.
Izinga lokuhamba kwe-MFR ye-PP isuka kwi-1 ukuya kwi-40. I-PP ene-MFR ephantsi inokumelana nempembelelo engcono kodwa amandla aphantsi aphantsi.Kwizinto eziphathekayo ezine-MFR efanayo, amandla ohlobo lwe-copolymer aphezulu kunohlobo lwe-homopolymer.Ngenxa yecrystallization, izinga lokucutheka kwePP liphezulu kakhulu, ngokubanzi 1.8-2.5%.Kwaye ukufana kolwalathiso lwe-shrinkage kungcono kakhulu kune-PE-HD kunye nezinye izinto.Ukongeza i-30% ye-glass additive inokunciphisa i-shrinkage kwi-0.7%.
Uhlobo lwe-homopolymer kunye nohlobo lwe-copolymer yezixhobo ze-PP zinokuxhathisa ukufuma okugqwesileyo, ukuxhathisa kwe-asidi-base-corrosion kunye nokumelana nokupheliswa.Nangona kunjalo, ayinakumelana ne-hydrocarbon enuka kamnandi (efana ne-benzene) kunye ne-chlorinated hydrocarbon (i-carbon tetrachloride) yokunyibilikisa.I-PP ayinayo ukumelana ne-oxidation kwiqondo lokushisa eliphezulu njenge-PE.
Ngokwale ntsebenzo ingasentla, iPP ifanelekile kwezi mveliso zilandelayo:
1. Isitofu: iivalvu, izincedisi, iikhreyithi, iimoto, izinto ezivaliweyo, izixhobo zombane, iibhotile zamanzi, Izikhongozeli zokutya, iimpahla zendlu, iithoyi, iisirinji ezingazaliswanga kwangaphambili.
2. Extrusion: sheet sheet, sheet, pipe, straw, tape yokubopha, iphepha lokubhala, i-BOPP film Sheet kunye nomcu.
3. Ukubumba ukuvuthela: ibhotile.
4. Thermoforming: itreyi, isitya, ikomityi yejeli, ikomityi yamanzi.
5. Umsonto osicaba: ibhegi elukiweyo, ingxowa yesingxobo, ikhaphethi.
