Kodi pepala la PP ndi chiyani?

Bolodi la PP, lomwe limadziwikanso kuti Polypropylene (ma pp) bolodi (PP Oyeretsa), Board ya PP, PP Exctor Board, PP Electrode), ndi zinthu za mazira a Semi-Crystalline. Zimakhala zovuta ndipo zimakhala ndi malo okwera kuposa pe. Popeza kutentha kwa mtundu wa ma PP ku Breyolymer kuli pamwamba pa 0 ° C, zinthu zambiri zamalonda ndizosasinthika ndi 1-5% ethylene kapena ethylene.

Yambitsitsani:

Dzina lazogulitsa: Zinthu za PP Cop Potolymer zili ndi kutentha kochepa kutentha (kuwonekera kwa 100 c), kuwonekera kotsika, kutsika pang'ono, koma kuli ndi mphamvu yolimba. Mphamvu ya PP imawonjezeka monga momwe zinthu zilili za Ethylene zimawonjezera. Kutentha kwa VCAAT ku Vicat Kutentha kwa PP ndi 150 ° C. Chifukwa cha kuchuluka kwa crystallity, nkhaniyi imakhala ndi nkhawa kwambiri komanso kukana. Palibe kutsindika kwachilengedwe kumalepheretsa vuto ku PP. Nthawi zambiri, ma pp amasinthidwa ndi kuwonjezera ulusi wamagalasi, zowonjezera zitsulo kapena rabar. Kuchuluka kwa ma pp ali ndi MFR kuyambira 1 mpaka 40. Otsika a MFR PP ali ndi zabwino zakutsutsa koma kutsikira. Zida za Mfr yemweyo, mphamvu ya mtundu wa wopopera ndiyokwera kuposa mtundu wa homopolymer. Chifukwa cha Crystallization, kuchuluka kwa shring'ona kwa ma pp ndikokwera kwambiri, nthawi zambiri 1.8%. Ndipo malangizo ofanana a shradege ndi abwino kwambiri kuposa zida monga PE-HD. Zowonjezera za 30% yagalasi imatha kuchepetsa shrazage mpaka 0.7%. Mtundu wonse wa Homepolymer ndi Comprolymer mtundu wa PP ali ndi njira zabwino kwambiri zotsutsana, acid ndi alkali kuphuka, ndi kukana kusagwirizana. Komabe, sikumalimbana ndi ma hydrocarbons opangira ma hydrocarbons monga Benzanel, chlorinated hydrocarbons (kaboni tetrachloride) ma sol sol, ndi zina. PP ilibe kukana kwa oxidation pa kutentha kwambiri ngati pe.

Gulu:

1.Pare PP Bodi: Kuchulukitsa kochepa, kosavuta kuwira ndi njira, kukana kwa mankhwala, kukana kwa madzi komanso kugonana, osawoneka bwino kwambiri

2.Palypropylene (pp) pepala lotalika: Ndi pepala la pulasitiki lopangidwa ndi kuwonjezera pp owonjezera osiyanasiyana owonjezera poyambira, ozizira, ozizira, kudula ndi njira zina.

3.glass fibern PP Bodi Yotsimikizika: Board FieldForth PP (BRPP Bodi): Atalimbikitsidwa ndi 20%, kuwonjezera pa kukonzanso maske, ndipo ali kusintha kwa kutentha komanso kutentha kochepa. , anti-Corlus ndi Arc kukana, shrankage yotsika. Makamaka fiber fiber, chlor-alkali, petroleum, matope, mankhwala ophera tizilombo, chakudya, mankhwala, mankhwala owala, zitsulo, zokongoletsera zina ndi minda ina.

4. Bolodi la bolodi, beta (β) -pphh sindere-stwint yoyera. (β) - Zogulitsa Zakhala zikugwiritsidwa ntchito bwino popanga zitsulo zam'mapepala, ndipo ukadaulo wapamwamba umakhala pamalo otsogola ku China. Zinthu izi zitha kugwiritsidwa ntchito mu mbale zosefera ndi zikwama zophukusira zophukira, zokhala ndi zilonda za perrochemical zosungira ndi mayendedwe, zomera zam'madzi, mankhwala amadzi, njira zamadzimadzi; Ndipo mbewu zachitsulo, zomera zamphamvu zimachokera kufumbi, kuchapa ndi mpweya wabwino, etc.

Ntchito:

PP yotakatalika ili ndi mawonekedwe olemera olemera, makulidwe a yunifolomu, osalala pokana, kukhazikika kwa makina apamwamba, kusokonezeka kwa mankhwala komanso kusakayika. Board Board imagwiritsidwa ntchito kwambiri mumitundu yamafuta, makina, zamagetsi, zida zamagetsi, mapangidwe a chakudya, mankhwala, zokongoletsera, zokongoletsera ndi mankhwalawa. Kutentha kwa mbale ya PP kumatha kufikira madigiri 100.

Zida za 1.Cid ndi Alkalinid ndi alkali, zida zamagetsi, zida zamagetsi za dzuwa, zida zotchinga zachilengedwe, zipinda zotumphukira, zida zonunkhira zopangidwa ndi mapulasitiki, ndizomwe zimakonda kupanga pulasitiki Matanki Madzi, omwe PP imagwiritsidwa ntchito kwambiri pakupumira m'magulu opusizira matchesi, ma boti a matress, etc.

2. Kubwezeretsanso mabatani, kuphatikizanso mabatani obwezeretsanso, zipatso ndi mabokosi opangira masamba, mabanki osungira, ndi mabokosi a stationer mu mafakitale osiyanasiyana;

3. Ma boloni a mafakitale, kuphatikiza waya ndi chingwe chotetezedwa, galasi, kutetezedwa ndi zinthu zosiyanasiyana, mashelufu, mashelufu, mbale, pansi mbale, mbale.;

4. Kuteteza, nthawi yomanga zomangamanga pomanga makatoni ndi plywood yapita kwamuyaya. Ndi kupita patsogolo kwa nthawi ndi kusintha kwa kukoma, kuonetsetsa kuti kukhulupirika kwa kapangidwe kakonzedwe katsoka chisanachitike, kutetezedwa koyenera kuyenera kuperekedwa kuti achite opareshoni. Zachuma, zotetezeka komanso zosavuta, komanso kutetezedwa kwa okweramo ndi pansi asanavomerezedwe.

5. Kuteteza magetsi. Zinthu zomwe zimapangitsa kuti zizigwira ntchito makamaka popanga zamagetsi monga chimfine, ma phukusi, maptoect, osokoneza bongo, osokoneza bongo oyambitsidwa. Palinso chidwi, mapapu pulasitiki, amatero ndi zina zotero. Buku la PP likhoza kugwiritsidwa ntchito kuwonjezera pa zomwe zili pamwambazi, komanso kumbuyo kwa makina ochapira, firiji yotukula, chakudya, shuga ndi kunyamula kwina. Mzere wopanga Hoflolod ukhoza kugwiritsidwanso ntchito kuti apange pelebodi matabwa kuti apereke zigawenga za malo osokoneza bongo zomwe zimafunikira ku madera omanga ndi kumidzi.

Kukula kwake:

Kukula kwa pepala la PP lopangidwa ndi pulasitiki ya Ahd:

Pp-H pepala, kukula: 1000 × 2000mm, 1220 × 2440mm, 500mm, 610 t: 1-----

PP- (C + H) pepala, Kukula: 1000 × 2000mm, 1220 × 2400mm, 1000mm t: 1 ----
