Kunyangwe mapurasitiki aine hunhu hwakawanda hwakanaka, haasi marudzi ese epurasitiki anogona kuva nehunhu hwakanaka. Mainjiniya emidziyo nevagadziri vemaindasitiri vanofanirwa kunzwisisa hunhu hwemapurasitiki akasiyana-siyana kuti vagadzire zvigadzirwa zvepurasitiki zvakakwana. Hunhu hwepurasitiki, hunogona kukamurwa kuita hunhu hwepakutanga, hunhu hwemakanika, hunhu hwekupisa, hunhu hwemakemikari, hunhu hweoptical uye hunhu hwemagetsi, nezvimwewo. Mapurasitiki einjiniya anoreva mapurasitiki eindasitiri anoshandiswa sezvikamu zvemaindasitiri kana zvinhu zveganda. Iwo mapurasitiki ane simba rakanaka, anodzivirira kukanganiswa, anodzivirira kupisa, akaomarara uye hunhu hwekudzivirira kukwegura. Indasitiri yeJapan ichaitsanangura se "inogona kushandiswa sezvikamu zvemapurasitiki zvinoshanda zvakanyanya, anodzivirira kupisa pamusoro pe100℃, anonyanya kushandiswa muindasitiri".
Pazasi tichanyora zvimwe zvinowanzoshandiswazvishandiso zvekuyedza:
1.Nhamba Yekuyerera Kwakanyunguduka(MFI):
Inoshandiswa kuyera mwero wekunyunguduka kwemvura (MFR) yemapurasitiki akasiyana-siyana nemaresini ari mumamiriro ekuyerera kwemvura. Yakakodzera mapurasitiki ekugadzira akadai sepolycarbonate, polyarylsulfone, fluorine plastiki, nylon nezvimwewo zvine tembiricha yakakwira yekunyunguduka. Yakakodzerawo polyethylene (PE), polystyrene (PS), polypropylene (PP), ABS resin, polyformaldehyde (POM), polycarbonate (PC) resin nedzimwe tembiricha yekunyunguduka kwepurasitiki ndiyo bvunzo yakaderera. Sangana nezvinodiwa: ISO 1133, ASTM D1238, GB/T3682
Nzira yekuedza ndeyekurega zvidimbu zvepurasitiki zvichinyunguduka kuita mvura yepurasitiki mukati menguva yakati (maminetsi gumi), pasi petembiricha yakati uye kumanikidzwa (miyero yakasiyana yezvinhu zvakasiyana), uye yozobuda nepakati pedhayamita ye2.095mm yehuwandu hwemagiramu (g). Kana kukosha kwacho kukuru, kuwanda kwemvura inoshandiswa mupurasitiki kunowedzera, uye zvinopesana. Standard yekuedza inonyanya kushandiswa iASTM D 1238. Chishandiso chekuyera cheiyi standard yekuedza iMelt Indexer. Maitiro chaiwo ekushanda kwekuyedza ndeekuti: zvinhu zvepolymer (purasitiki) zvinofanirwa kuyedzwa zvinoiswa mugoronga diki, uye mugumo wegoronga wakabatana nechubhu yakatetepa, dhayamita yayo iri 2.095mm, uye kureba kwechubhu iri 8mm. Mushure mekudziya kusvika patembiricha yakati, mugumo wepamusoro wezvinhu zvakabikwa unodzvanywa pasi nehuremu hwakati hunoshandiswa nepiston, uye huremu hwezvinhu zvakabikwa hunoyerwa mukati memaminitsi gumi, inova indekisi yekuyerera kwepurasitiki. Dzimwe nguva uchaona mufananidzo weMI25g/10min, zvinoreva kuti magiramu makumi maviri nemashanu epurasitiki aburitswa mumaminitsi gumi. MI kukosha kwemapurasitiki anoshandiswa kazhinji kuri pakati pe1 ne25. MI yakakura, viscosity yezvinhu zvakabikwa zvepurasitiki idiki uye huremu hwemamorekuru hudiki; zvikasadaro, viscosity yepurasitiki yakakura uye huremu hwemamorekuru hunowedzera.
2.Muchina weKuedza Tensile Wese (UTM)
Muchina wekuyedza zvinhu zvepasi rose (muchina wekukwesha): kuyedza kukwesha, kubvarura, kukotama nezvimwe zvinhu zvepurasitiki.
Inogona kukamurwa kuita zvikamu zvinotevera:
1)Simba rekusimba&Kureba:
Simba rekudhonza, iro rinozivikanwawo sesimba rekudhonza, rinoreva hukuru hwesimba rinodiwa kuti zvinhu zvepurasitiki zvitambanudzwe kusvika pamwero wakati, rinowanzo tsanangurwa zvichienderana nekuti simba rakawanda sei panzvimbo imwe neimwe, uye huwandu hwehurefu hwekudhonza ndihwo hurefu. Simba rekudhonza Kumhanya kwekudhonza kwemuenzaniso kunowanzova 5.0 ~ 6.5mm/min. Nzira yekuyedza yakadzama zvichienderana neASTM D638.
2)Simba rinochinjika&Simba rekukotama:
Simba rekukotama, iro rinozivikanwawo sesimba rekukotama, rinonyanya kushandiswa kuona simba rekukotama remapurasitiki. Rinogona kuyedzwa zvichienderana nenzira yeASTMD790 uye rinowanzo ratidzwa zvichienderana nekuti simba rakawanda sei pachikamu chimwe nechimwe. Mapurasitiki akajairika ePVC, Melamine resin, epoxy resin uye simba rekukotama repolyester ndiwo akanakisa. Fiberglass inoshandiswawo kuvandudza simba rekukotama remapurasitiki. Kukotama kunoreva kushushikana kwekukotama kunokonzerwa nehuwandu hwekuchinja kwechikamu chimwe nechimwe kana sampuli yakakotama (nzira yekuyedza senge simba rekukotama). Kazhinji, kana kukotama kwakakura, kuomarara kwezvinhu zvepurasitiki kuri nani.
3)Simba rekumanikidza:
Simba rekudzvanya rinoreva kugona kwepurasitiki kutsungirira simba rekudzvanya rekunze. Kukosha kwekuyedza kunogona kuonekwa zvichienderana nenzira yeASTMD695. Polyacetal, polyester, acrylic, urethral resins uye meramin resins zvine hunhu hwakanaka panyaya iyi.
3.Muchina wekuyedza kukanganisa kweCantilever/ Smuchina wekuyedza mhedzisiro yemwaranzi unotsigirwa nechiedza
Inoshandiswa pakuedza kusimba kwesimba rezvinhu zvisiri zvesimbi zvakaita sepurasitiki yakaoma, pombi, zvinhu zvakagadzirwa nechimiro chakasarudzika, nylon yakasimbiswa, purasitiki yakasimbiswa nefiber yegirazi, ceramic, zvinhu zvinodzivirira magetsi zvematombo akaumbwa, nezvimwewo.
Zvichienderana nechiyero chepasi rose cheISO180-1992 "kuongorora simba remuchina wepurasitiki - zvinhu zvakaoma"; Standard yenyika yeGB/ T1843-1996 "nzira yekuyedza muchina wepurasitiki wakaoma", standard yeindasitiri yemakanika JB/ T8761-1998 "muchina wekuyedza muchina wepurasitiki wekudzivirira muchina".
4. Miedzo yezvakatipoteredza: kutevedzera kuramba kwemamiriro ekunze kwezvinhu.
1) Muchina wekuyedza tembiricha inogara iripo, muchina wekuyedza tembiricha uye hunyoro nguva dzose unoshanda mumidziyo yemagetsi, ndege, mota, midziyo yemumba, pendi, indasitiri yemakemikari, tsvakurudzo yesainzi munzvimbo dzakadai sekugadzikana kwemidziyo yekuyedza tembiricha uye hunyoro, inodiwa kune zvikamu zveindasitiri, zvikamu zvekutanga, zvigadzirwa zvakapedzwa zvishoma, zvemagetsi, zvemagetsi nezvimwe zvigadzirwa, zvikamu nezvinhu zvetembiricha yepamusoro, tembiricha yakaderera, kutonhora, hunyoro uye kupisa kana bvunzo yenguva dzose yetembiricha uye hunyoro nharaunda.
2) Bhokisi rekuyedza kukwegura nemazvo, Bhokisi rekuyedza kukwegura kweUV (mwenje we ultraviolet), Bhokisi rekuyedza kutonhora kwakanyanya uye kwakaderera,
3) Chirongwa cheThermal Shock Tester chinorongwa
4) Muchina wekuyedza kutonhora uye kupisa unoshandiswa mumagetsi nemagetsi, ndege, mota, midziyo yemumba, machira, indasitiri yemakemikari, indasitiri yekudzivirira nyika, indasitiri yemauto, tsvakurudzo yesainzi nedzimwe nzvimbo, michina yekuyedza inodiwa, yakakodzera kushandurwa kwemuviri kwezvikamu nezvinhu zvezvimwe zvigadzirwa zvakaita se photoelectric, semiconductor, zvikamu zvine chekuita nemagetsi, zvikamu zvemotokari neindasitiri dzine chekuita nemakombiyuta kuyedza kuramba kwezvinhu kakawanda kusvika pakupisa kwakanyanya uye kwakaderera uye shanduko dzemakemikari kana kukuvara kwemuviri kwezvigadzirwa panguva yekuwedzera kwekupisa uye kudzikira kwechando.
5) Kamuri rekuyedza rinochinja-chinja tembiricha yepamusoro neyakaderera
