PVC (Polyvinyl Chloride)

Chemical uye Zvepanyama Zvivakwa: Rigid PVC ndechimwe chezvinhu zvakanyanyisa kushandiswa zvepurasitiki. PVC ndeye isiri-crystalline zvinhu. PVC inowanzoshandiswa neStabilizers, maLubricants, proceliary processors, colorants, imbi enziyo uye zvimwe zvinowedzera. PVC haina-kupenya, simba rakanyanya, kuramba kuchinjika kuchinjika, uye zvakanakisa geometrical kusimba. PVC inodzivirira zvakanyanya kune oxidizing vamiririri, kudzora vamiririri, uye acids yakasimba. PVC inodzivirira zvakanyanya kune oxidizing vamiririri, kuderedza vamiririri uye zvakashata acids. Nekudaro, zvinogona kugadzirwa ne oxidizing acids yakadai seyakafanana neslfunding acid, yakakwaniswa nitrate ma hydrocarbons.Haripi tembiricha yePVC yakakosha procer paramende kana uchigadzirisa, uye kana izvi Paramende haina kukodzera, ichatungamira kudambudziko rekuenda kwezvinhu zvemidziyo. Kunyanya hombe molecular huremu hwePVC zvinhu zvakanyanyisa kuoma (izvi zvinhu zvinowanzoda kuwedzera maLubriants kuti uwedzere hunhu hwePVC .VC shrinkage ndeye yakaderera, kazhinji 0.2 ~ 0.6%.

Pe (polyethylene)

A. Ko iko kugadzirwa kukuru kwepasirese, mapurasitiki anoshandiswa zvakanyanya, kugadzirwa kwayo kwakarondedzera kwe30% yePlastics yenyika

B. Chimiro chayo chidimbu cheketeni refu kana cheni chetembe, ndeyechemaginel crystalline polymer

C. Wuchang Isiri-ine chepfu kusagadzikana kupisa chena poda, kutaridzika kwekuyerera kuchena

D. Yakanakisa yemagetsi insulation zvivakwa, yakakodzera kune yakakwira-frequency tambo insulation layer

E. Yakakwirira Chemical Kugadzikana

F. Yakanaka-famba-tembiricha kuramba, inogona kugadzirwa nefirimu yekurima, mapaketi ekurongedza

Pe-hd (yakakwira-density polyethylene, inowanzozivikanwa seyakaoma nyoro rabara, kailex)

Kupokana nekurovera kutonhora uye kupisa musimba musimba, kuomarara kwakanyanya, kutonhora kutonhora kupokana, kupisa kupisa kupisa tembiricha, kusavimbika kuramba.

Iyo yakakurumbira yakanaka magetsi, kuita zvemakemikari zviri nani pane yakakwirira-kumanikidza Polyethylene, Solubility iri nani solvent (kunze kwemasishini mashoma anogona kujekesa, pamwe nekushomeka, kuwedzera gamu, acid .

Kunyorova kunyorova zvidiki, handidi kuoma, kufara kwekudzvinyirira kwekudzvinyirira, kudzikisira uye kupatsanura kureba kukosora kwakakura jekiseni, isina kukodzera gedhi rakatwasuka, yakapfava uye iri nyore kuburitsa chiumbwa.

Cemical uye Peficers: Pe-HD's Yakakwirira yekwenya inotungamira kune yakakwira density, kusimba kwesimba, visikoka, Yakadzika.Pe-HD Zvivakwa zvinonyanya kudzorwa nehuremu uye molecular uremu kugoverwa. Iyo molecular uremu kugoverwa kwePE-HD yakakodzera kuti jekerere kuumbwa kwakanyanya. Yeiyo density ye 0.91 ~ 0.925g / cm3, tinozvidaidza iyo yekutanga mhando ye-pe-hd; ye 0.926 ~ 0.94g / cm3, tinozvidaidza iyo yechipiri mhando ye pe-hd; Kune density ye 0.94 ~ 0.965g / cm3. Isu tinoidaidza iyo yechitatu rudzi rwe pe-hd. Izvo zvinyorwa zvine yakanaka kwazvo maitiro, neye mfr ye 0,1 kusvika 28. yakakwira iyo smecular uremu, iyo iyo ph-ld ine yakadzika simba rekukanganisa. Yakakwira iyo molecular uremu, hurombo iyo inoyerera zvivakwa zvePH-LD, INE ISE PLECATINE ISANGANO uye ine yakakwira shrinkage mushure mekuumbwa, pakati pe1.5 uye 4% .pe-hd inokanganiswa Kushushikana kwezvakatipoteredza kupaza. Kupwanya kunogona kuderedzwa nekushandisa zvinhu zvakanyanyisa kuyerera maitiro kuti udzikise mukushushikana kwemukati

Pe-ld (yakaderera density polyethylene, inowanzozivikanwa seye nyoro rabha, ruva remaruva, tube zvinyorwa)

Low Sychenical Properties, kupfava, Kuwedzera Kukanganisika, kujekesa kweHorviniti kwakarongedzwa, kuwanda-kurongedza midziyo, majasi, waya uye tambo yekuputika uye yakapfava jekiseni kuumbwa , zvikamu zvekunze.

Yakanakisa magetsi emisangano yekunamatira uye kumakemikari kurwisa, kuwedzera gamu kuora, acid uye alkali kuramba (kunze kweiyo nitric nitric acid), zvakanaka dielectric zvivakwa. Nyore kuumbwa.

Kemical uye Yenyama Zvivakwa: Iyo density yeCommerce Pe-LD zvinyorwa ndeye 0.94g / cm3. Pe-ld inogamuchirwa kugesi uye mupfu wemvura. Iyo coefficient yekuwedzera kwekuwedzera kwePe-ld iri yakanyanya kusarudzika yekugadzirisa kwekushandiswa kwenguva refu kwezvigadzirwa. Kana density ye-pe-ld iri pakati pe0,91 ~ 0.924g / cm3, ipapo iyo shrinkage chiyero chiri pakati pe2-5%; Kana density iri pakati pe0926 ~ 0.94g / cm3, saka iyo shrinkage chiyero chiri pakati pe1,5% ~ 4%. Iyo chaiyoiyo ino shringe chiyero zvakare neiyo jekiseni kuumbwa maitiro.Pe-ld inopesana nemamiriro ekunze ekushisa, asi zvinonyangadza uye chlorin Zvakafanana nePE-HD, PLD ANOGONESESWA KUTI KUTI KUTI UTSHURE KUSANGANO YEMAHARA.

Pp (polypropylene, inowanzozivikanwa sePolypropylene)

Iyo ndeimwe yeanonyanya kupisa-simba-inodzivirira-geny-geny-genstled simba rekubereka uye hupenyu hwakanyanya hwekuita hupenyu hwepamoyo hupenyu. Shrinkage yakakura, kukanganisa simba kuchinja nekushisa tembiricha, kuomarara hakuna kukwana, kupisa.

Nzvimbo dzakagadzikana chemakemikari, dzine madhiza akanaka emakemikari, anogona kutsungirira madhigirii masere pazasi peiyo ACORANIC ACIDS, Alkalis, munyu uye nyanzvi zhinji dzemvura.

Iyo ine tsvina yakanaka pasi pekunyungudika pfungwa uye kwakanaka kuumbwa kuita.

Chemical uye Yenyama Zvivakwa: PP ndeye SERI-Crystalline zvinhu, zvakaoma kupfuura pe uye ine poindi yakakwira. Nekuti Homopolymer-Type PP ine tembiricha pamusoro 0 Debrees Celsius Copolymer-Type PP Zvigadziko Zvekupedza kukanganisa Nekuda kweiyo yakakwirira crystallinity, urwu rwemhando yemiriwo mbiri oh socurness uye scratch kuramba hunhu hwakanaka kwazvo.PP haina mamiriro ekunze Kazhinji, pp inogadziridzwa negirazi fiber, simbi inowedzera kana thermoplastic rabha. Kune iyo mfr yakafanana, iyo yeCoplymer mhando yakasimba kupfuura iyo mheremhere yemhando yemhando. Nekuda kwekuchema, kuderera kwePP kwakakura kwazvo, kazhinji 1.8 kusvika ku2,5%. Uye kufanana kwatakareva kwekudzikira kuri nani pane zvigadzirwa zvakaita se pe-hd. Kuwedzera makumi matatu muzana egirazi inowedzera inogona kuderedza iyo shringerge kusvika ku0,7%. Ose homopolymer-rudzi uye ecolymer-mhando pP zvigadzirwa zvine simba rakanyanya kukunyorera, asidhi naAlkali kuronga, uye solubility. Nekudaro, haina kupokana neiyo inonhuhwirira hydrocarbon (semuenzaniso, benzene) sol soldrocarbon (carloned tetrachloride)

PP PELYPROPLEE ETSYLEE

Chemical uye Zvepanyama Zvivakwa: Kazhinji, zvekutengesa PPPE PPPO kana PPPO ZVINHU ZVINOGONESESWA NEZVINHU ZVAKAWANDA SEPS, PA, et, et. Izvi zvinosanganiswa zvichiri kuwanzotaurwa sezvinoita ppe kana ppo. Kusanganiswa ppe kana ppo ine zvakawanda zviri nani kugadzirisa maitiro kupfuura izvo zvakachena zvinhu. Kusiyana kwezvivakwa kunoenderana neiyo chiyero chezvisungo zvakadai sePPO kusvika Ps. Kusanganiswa zvigadzirwa ne pa66 vane yakakwira makemikari kugadzikana pakukwirira kwakanyanya. Izvo zvinyorwa zvine yakaderera kwazvo hygroscopiciticity uye zvigadzirwa zvine yakanakisa geometrical kusimba. Iyo PS yasanganisira isina-crystalline, nepo pairi iyo iri bliss crystalline. Shrinkage inogona kuderedzwa kusvika 0,2% nekuwedzera girazi fiber anowedzera. Izvo zvinyorwa zvakare zvine zvemagetsi zvakanakisa zvekusimbisa zvinhu uye kuenderana zvakanyanya nekuwedzera kwekuwedzera kwekuwedzera. Iyo visikopa inoenderana nehuremu hwemusanganiswa mune izvo zvinyorwa, uye kuwedzera kweiyo chiyero chePPO chinotungamira kune kuwedzera kwe viscosity.
