PMMA (Polymethylmethacrylate, inowanzozivikanwa seAcrylic)

Makemikari uye zvivakwa zvemuviri:

PMMA ine zvakanakisa zvemakemikari zvivakwa uye mamiriro ekunze ekuchinja kuramba. Iyo yekupinda yeiyo chena mwenje yakakwira se92%. PMMA MABHUKU ANOGADZA ZVAKAWANDA BELIDEFRINCENCENCENCENCE UYE ZVINONYANYA KUKOSHESA KUTI VAVHURE, nezvimwe. Sezvo mutoro unowedzera uye nguva inowedzera, kushushikana kwekupaza kunogona kuitika. PMMA ine yakanaka yekukanganisa kuramba zvinhu.

Yakakwirira Yakasimba Kugadzikana, Runako Kupesana, Kupokana, kusimbisa kwakanaka, kuenzanisa kweiyo Aluminium . Kwete kuramba kusvika kune yakasimba sulfutic acid, yakasimba nitric acid, yakasimba alkali, cottones, fetiraiza soluble mune inonhuwira hydrocarbons uye mamwe organic sol.

Nyoro yakaderera, zvidiki zvekuumbwa shringer, yakakwira dimensional kugadzikana, kusarongeka kwekunyoresa kugadzikana, yakakwira melt viscosity.

PA6 Polyamide 6 kana nylon 6

Simba rakakwirira rekusimba, runako runyararo, rakanyanya kuoma uye simba rekumanikidza, kusimba kwakasimba kusanganisa kukanganisa, kupfeka, kupfeka kupokana, kusaneta, kushaya chepfu, zviri nyore kuumba.

Corrosion-inodzivirira uye yakanaka kwazvo yemagetsi clorine mashandiro.

Zviri nyore kutora mvura, ine hurema hwokupokana zvachose, ine huremu hukuru hwemanyorerwe uye inogona kukandwa muNylon. Iyo ine simba rakanyanya uye rinogona kushandiswa kuumba kuomarara kuumba kana zvidiki zvidiki.

Makemikari uye zvivakwa zvemuviri:

Iyo yemakemikari uye yemuviri zvivakwa pa6 zvakafanana chaizvo ne pa66, zvisinei ine poindi yakadzika yekunyungudika uye yakawedzera tembiricha tembiricha. Kuroverana kwayo kurwisa uye kupatsanurwa kupesana kuri nani pane pa66, asi zvakare zvakare hygrapic. Nekuti hunhu hwakawanda hwezvikamu zvepurasitiki zvinokanganiswa nehyotroscopiciticoti, izvi zvinofanirwa kuve zvakazara mukufunga kana uchigadzira zvigadzirwa uchishandisa PA6. Kuti uvandudze michina yemakirini yePA6, akasiyana modifiers anowanzowedzerwa. Girazi ndiyo inonyanya kujairika, uye dzimwe nguva inynthetic rabha, yakadai seEpdm naSbrm, inowedzerwa kugadzirisa kukanganisa kukanganisa. Zvezvigadzirwa pasina zvekuwedzera, iyo shrinkage chiyero che pa6 iri pakati pe1 uye 1.5%. Kuwedzera girazi fiber ma-styitives kunogona kuderedza iyo shrinkage chiyero kusvika 0,3% (asi iri yakakwira zvishoma munzira iyo perpendicular kune maitiro). Iyo inodzikira chiyero chegungano yakaumbwa inonyanya kukanganiswa neicho crystallinity uye hygroscopicity yezvinyorwa. Iyo chaiyo shringer huwandu zvakare ibasa repurasitiki chikamu dhizaini, kurira kwemadziro uye mamwe ma parmeter.

Pa66 polyamide 66 kana nylon 66

Pa66 ine simba rakanyanya rekusimba pakati peplastics uye ndiyo yakanyanya kushandiswa zvakasiyana siyana. Iyo ine yakasimba crystallinity uye yakakwirira yakaoma uye inopisa zvinhu. Iyo ine yakakwira yakabikwa simba kupfuura pa6 uye pa610, uye mwero wekunyora we0,07. Iyo inopfekedza-inodzivirira uye ine simba rakakwirira kwazvo rekutambanudza ratidziro yekurapa.

Shamiswa nezvigadziko zvisina simba, pamwe, nemberi, ketoni napeteni; nyura mune phenol, yakaisvonaka sulfutic acid uye yakaderera molecular organic acids, ine point point yakaderera pane pa1010; viscosity yakaderera uye fluidity yakanaka.

Chemical uye Zvepanyama Zvivakwa : Pa66 ine nzvimbo yepamusoro yekunyungudika pakati pePolyamide zvinhu. Icho chidimbu-crystalline-crystalline zvinhu. Pa66 inogona kuchengetedza simba rakasimba uye kuomarara kune yakakwirira tembiricha. Paan anogara hygroscopic mushure mekuumbwa, iyo inoenderana zvakanyanya nekuumbwa kwemukati, ukobvu hwemadziro, uye mamiriro ezvinhu epakatiridzira. Paunenge uchigadzira zvigadzirwa, kukanganiswa kwehyotroscopicity pane geometric kugadzikana kunofanirwa kutariswa. Kuti uvandudze michina yemakanika ye pa66, modifiers dzakasiyana-siyana dzinowanzowedzerwa. Girazi ndiyo inonyanya kujairika, uye dzimwe nguva inynthetic rabha, yakadai seEpdm naSbrm, inowedzerwa kugadzirisa kukanganisa kukanganisa. Pa66 ine yakadzika viscosity, saka inoyerera zvakanaka (asi kwete pamwe ne pa6). Ichi chivakwa chinogona kushandiswa kugadzirisa zvinhu zvakatetepa. Viscosity yayo inonzwa kushanduka kwekushisa. Iyo shrinkage chiyero che pa66 iri pakati pe1 ne2%. Kuwedzera girazi fiber ma-styitives kunogona kuderedza iyo shrinkage chiyero kusvika 0.2 kusvika 1%. Musiyano wacho mu shrinkage rate munzira yekuita uye iyo nzira yepakati perpendicular kune iyo nzira yekutungamira yakakura. Pa66 inodzivirira kune akawanda manyorerwo, asi haakanganisike kuacids uye mamwe marudzi echiplorinating.

Pa12 polyamide 12 kana nylon 12

Chemical uye Yenyama Zvivakwa: PA12 ndeye mutsara, hafu-crystalline-crystalline thermoplastic zvinyorwa zvinobva kuButadiene. Zvivakwa zvayo zvakafanana ne pa11, asi chimiro chayo chekristaro chakasiyana. Pa12 ndeye yakanakisa yemagetsi magetsi uye seimwe polyamides haina kutakurwa nemunyoro uye yakagadziridzwa marudzi akasarudzika nezvivakwa zvinowedzerwa. Kuenzaniswa nePA6 uye PA66, izvi zvigadzirwa zvine message akanyungudutsa uye densities, uye uve nehunyoro hwakanyanya kuwanazve. Pa12 haina kuramba kune yakasimba oxidizing acids. Iyo viscosity ye pa12 inonyanya kuenderana nekunyorova, tembiricha uye nguva yekuchengetedza. Kubhururuka kwayo kwakanaka kwazvo, uye kuderera kwayo kuri pakati pe 0.5 uye 2%, iyo inonyanya kuenderana nemhando yemidziyo, madziro madziro uye mamwe mamiriro emamiriro ezvinhu.

PBT PolyTyley Terephthalate

Chemical uye Zvepanyama Zvivakwa: PBT ndechimwe cheiyo yekukwira injini yeinjiniya yechigadzirwa Icho chidimbu cheSemi-Crystalline nemidziyo yakanaka kwazvo yekugadzikana, masimba masimba, maitiro emagetsi ekusimbisa gadziriso uye kugadzikana kwekunyora. Izvi zvigadzirwa zvine chimiro chakanaka pamusoro pehuremu hwakasiyana hwemamiriro ekunze. Simba rePBT ndeye 170mpa. Zvakawanda zvegirazi zvinowedzera zvinokonzeresa kuti zvinyorwa zvive brittle. PBT: Crystallize nekukurumidza, iyo ichatungamira mukukotama deformation nekuda kwekutonhora kusingaonekwe. Zvekushandisa plexiglass extitive emhando yemhando, iyo shrinzwige mune yekuita nzira inogona kuderedzwa, asi kuderera munzira yepakati pane maitiro haana kusiyana nezvinhu zvakajairika. Kazhinji, iyo shrinkage rate yezvinhu zviri pakati pe1.5 ~ 2.8%. Iyo shrinkage rate yezvinhu zvine 30% magirazi egirazi ari pakati pe 0.3% uye 1.6%. Iyo yekunyungudika pfungwa (225 degrees) uye yakakwira-tembiricha yekushongedza tembiricha yakaderera pane mhuka yemhuka. Iko kupfava tembiricha yekadhi iri rinenge mazana matatu emadhigirii. Iyo girazi transition tembiricha (girazi transition tembiricha) iri pakati pemadhigiri makumi maviri nemaseti makumi mana nematanhatu. Nekuti PBT ine yakakwirira yekunyora kumhanya, viscosity yayo yakaderera kwazvo, uye nguva yekutenderera yePurasitiki zvikamu zvekugadzirisa zvinowanzo kuderera.

PC + ABF Chinyorwa

Zvakanakira:

1. Kuwedzera kusimba kupisa kupokana uye kudzikisira kugadzikana, kuvandudzwa PC yakadzika tembiricha, yakavandudzwa kumashure kwemadziro kukanganisa kuramba, uye kuderedzwa kwemitengo

2. Kuumbwa kwemuviri 3. Kuumbwa kwakanaka 4. Yakanakisa kukanganisa simba

Kuumbwa Performance: 1. Mutengo wezvinhu uri padyo neABS, asi zvivakwa zvemuviri zvakakwira kupfuura abs 2. Izvi zvinyorwa zvinopa kupisa kwakanyanya, tembiricha yakakwira uye yakakwirira simba rekushisa3. Kuita kwayo kwekuita kwakafanana neABS, asi kusiyana nePC, iyo yakanyanya kuoma kuti ibate Degree of hygroscopicity, uye urema senge mavara, moire, uye kupunzika kuchaitika pane chigadzirwa panguva yekuumbwa. Naizvozvo, kuoma kunofanirwa kuitwa usati waumbwa.
