Kunyange zvazvo mapurasitiki ane zvinhu zvakawanda zvakanaka, haasi marudzi ose epurasitiki anogona kuva nezvose zvakanaka. Mainjiniya ezvishandiso uye vanogadzira maindasitiri vanofanirwa kunzwisisa zvimiro zvemapurasitiki akasiyana kuitira kugadzira zvigadzirwa zvepurasitiki zvakakwana. Iyo midziyo yepurasitiki, inogona kukamurwa kuita zvinhu zvekutanga zvemuviri, midziyo yemuchina, midziyo yekupisa, chemikari pfuma, midziyo yemaziso uye midziyo yemagetsi, etc. Mapurasitiki euinjiniya anoreva mapurasitiki eindasitiri anoshandiswa sezvikamu zveindasitiri kana magoko. Iwo mapurasitiki ane simba rakanakisa, kukanganisa kwemaitiro, kupisa kupisa, kuoma uye anti-kuchembera zvivakwa. Indasitiri yeJapan ichaitsanangura se "inogona kushandiswa seyakaumbwa uye yemagetsi zvikamu zvemapurasitiki epamusoro-soro, kupisa kupisa pamusoro pe100 ℃, inonyanya kushandiswa muindasitiri".
Pazasi isu tichanyora zvimwe zvinowanzoshandiswakuyedza zvishandiso:
1.Melt Flow Index(MF):
Inoshandiswa kuyera kunyunguduka kuyerera kweMFR kukosha kwemapurasitiki akasiyana uye resin mune viscous flow state. Yakakodzera mapurasitiki einjiniya akadai sepolycarbonate, polyarylsulfone, fluorine mapurasitiki, naironi uye zvichingodaro nekushisa kwakanyanya kunyungudika. Uyewo akakodzera polyethylene (PE), polystyrene (PS), polypropylene (PP), ABS resin, polyformaldehyde (POM), polycarbonate (PC) resin uye mamwe epurasitiki kunyunguduka tembiricha yakaderera bvunzo. Sangana nezviyero: ISO 1133, ASTM D1238,GB/T3682
Nzira yekuyedza ndeyekusiya mapurasitiki anyunguduka mumvura yepurasitiki mukati meimwe nguva (maminetsi gumi), pasi peimwe tembiricha uye kudzvanywa (akasiyana zviyero zvezvinhu zvakasiyana-siyana), uye obva ayerera kunze kuburikidza ne2.095mm dhayamita yehuwandu hwemagiramu. (g). Iyo yakakura kukosha, zviri nani kugadzirisa liquidity yezvinhu zvepurasitiki, uye zvinopesana. Chiyero chinowanzo shandiswa chiyero ndeye ASTM D 1238. Chiyereso cheiyi chiyero chebvunzo ndeye Melt Indexer. Iyo chaiyo yekushanda maitiro ekuyedzwa ndeiyi: iyo polymer (yepurasitiki) zvinhu zvinoyedzwa inoiswa mudiki groove, uye kuguma kwegorofu kwakabatana nechubhu yakatetepa, dhayamita yaro i2.095mm, uye kureba chubhu iri 8mm. Mushure mekupisa kune imwe tembiricha, iyo yekumusoro yekupedzisira yeyakasvibirira inotsikirirwa pasi nehumwe huremu hunoshandiswa nepiston, uye huremu hweiyo mbishi hunoyerwa mukati memaminitsi gumi, inova indekisi yekuyerera yepurasitiki. Dzimwe nguva iwe uchaona inomiririra MI25g / 10min, zvinoreva kuti 25 magiramu epurasitiki akawedzerwa mumaminitsi gumi. Iyo MI kukosha kwepurasitiki inowanzoshandiswa iri pakati pe1 ne25. Iyo yakakura MI, iyo idiki iyo viscosity yepurasitiki yakasvibirira zvinhu uye madiki mamorekuru uremu; kana zvisina kudaro, iyo yakakura viscosity yepurasitiki uye yakakura iyo molecular uremu.
2. Universal Tensile Testing Machine (UTM)
Universal material yekuyedza muchina (tensile muchina): kuyedza kusimba, kubvarura, kukotama uye zvimwe zvemichina zvinhu zvepurasitiki zvinhu.
Inogona kugoverwa muzvikamu zvinotevera:
1)Kusimba simba&Elongation:
Simba rekusimba, rinozivikanwawo sesimba rekusimba, rinoreva saizi yesimba rinodiwa kutambanudza zvinhu zvepurasitiki kusvika padanho rakati, rinowanzo kuratidzwa maererano nehuwandu hwesimba pachikamu cheyuniti, uye chikamu chekureba kwekureba. Kusimba kwesimba Kumhanya kwekumhanya kwemuenzaniso kunowanzoita 5.0 ~ 6.5mm/min. Yakadzama yekuyedza nzira zvinoenderana neASTM D638.
2)Flexual simba&Kupeta simba:
Simba rekubhenda, iro rinozivikanwawo se flexural simba, rinonyanya kushandiswa kuona flexural resistance yemapurasitiki. Inogona kuyedzwa zvinoenderana neASTMD790 nzira uye inowanzo ratidzwa maererano nehuwandu hwesimba pane imwe unit nzvimbo. General mapurasitiki kuPVC, Melamine resin, epoxy resin uye polyester kubhenda simba ndiyo yakanyanya kunaka. Fiberglass inoshandiswawo kuvandudza kupeta kuramba kwepurasitiki. Kubhenda elasticity kunoreva kubhenda kushushikana kunogadzirwa pachiyero cheyuniti ye deformation mu elastic renji kana muenzaniso wakakotama (yebvunzo nzira senge simba rekukotama). Kazhinji, iyo yakakura kubhenda elasticity, zviri nani kuomarara kwepurasitiki zvinhu.
3)Kudzvinyirira simba:
Kutsikirira simba kunoreva kugona kwemapurasitiki kushingirira kunze kwekumanikidza simba. Iko kukosha kwekuyedza kunogona kutsanangurwa zvinoenderana neASTMD695 nzira. Polyacetal, polyester, acrylic, urethral resins uye meramin resins zvine hunhu hwakatanhamara mune izvi.
3.Cantilever impact yekuyedza muchina/ Szvinoreva inotsigirwa beam impact yekuyedza muchina
Inoshandiswa kuyedza kuomarara kwezvinhu zvisiri zvesimbi senge pepa repurasitiki rakaoma, pombi, yakasarudzika-yakaumbwa zvinhu, yakasimbiswa naironi, girazi fiber yakasimbiswa purasitiki, ceramic, dombo rakakandwa remagetsi insulating zvinhu, nezvimwe.
Zvinoenderana neyakajairwa pasi rose ISO180-1992 "purasitiki - yakaoma zvinhu cantilever inokanganisa kusimba kwesimba"; Iyo yenyika yakajairwa GB/ T1843-1996 "yakaoma plastiki cantilever kukanganisa bvunzo nzira", iyo mechaniki indasitiri yakajairwa JB/ T8761-1998 "plastiki cantilever impact yekuyedza muchina".
4.Environmental tests: kuenzanisa kupikisa kwemamiriro ekunze kwezvinhu.
1) Kugara tembiricha incubator, tembiricha yenguva dzose uye humidity yekuyedza muchina midziyo yemagetsi, aerospace, mota, midziyo yemumba, pendi, indasitiri yemakemikari, tsvakiridzo yesainzi munzvimbo dzakaita sekugadzikana kwekushisa uye humidity yekuongorora michina, inodiwa kune zvikamu zveindasitiri, zvikamu zvekutanga, semi-akapedza zvigadzirwa, magetsi, zvemagetsi uye zvimwe zvigadzirwa, zvikamu uye zvinhu zvekushisa kwakanyanya, tembiricha yakaderera, kutonhora, kunyorova uye kupisa dhigirii kana bvunzo yenguva dzose yekudziya uye humidity nharaunda bvunzo.
2) Precision kuchembera bvunzo bhokisi, UV kuchembera bvunzo bhokisi (ultraviolet chiedza), yakakwirira uye yakaderera tembiricha bvunzo bhokisi,
3)Programmable Thermal Shock Tester
4) Kutonhora nekupisa kwemagetsi ekuyedza midziyo yemagetsi nemagetsi, ndege, mota, midziyo yemumba, machira, indasitiri yemakemikari, indasitiri yedziviriro yenyika, indasitiri yemauto, tsvakiridzo yesainzi uye mamwe minda inodiwa bvunzo michina, Yakakodzera shanduko yemuviri zvikamu uye zvigadzirwa zvezvimwe zvigadzirwa senge photoelectric, semiconductor, zvemagetsi zvine chekuita nemagetsi, zvikamu zvemotokari uye maindasitiri ane hukama nemakomputa kuyedza kuramba kudzokororwa kwezvinhu kusvika kumusoro uye kwakadzika tembiricha uye shanduko yemakemikari kana kukuvadzwa kwemuviri kwezvigadzirwa panguva yekuwedzera kwekupisa uye kutonhora. .
5) High uye yakaderera tembiricha alternating test room
6)Xenon-lamp Weather Resistance Test Chamber
7)HDT VICAT TESTER
