TPR ine zvinotevera zvakanakira: (1) Inogona kugadziriswa neyakajairwa thermoplastic molding michina, senge jekiseni kuumba, extrusion molding, blow molding, compression molding, uye mold transfer molding;(2) Inogona kupiswa nerabha jekiseni rekugadzira muchina, uye nguva inogona kupfupikiswa kubva pa20min kusvika isingasviki 1min;(3) Inogona kuumbwa uye vulcanized nemuchina, nekukurumidza kudzvanya kumhanya uye pfupi vulcanization nguva;(4) Tsvina inogadzirwa mukugadzira (kupukunyuka maburrs uye extruding tsvina rabha) uye yekupedzisira tsvina inogona kudzoserwa zvakananga kuti ishandiswe zvakare: (5) Yakashandiswa TPR zvigadzirwa zvekare zvinogona kungoshandiswa zvakare uye kushandiswa zvakare kuderedza kusvibiswa kwezvakatipoteredza uye kuwedzera. tsime rekuvandudza zviwanikwa;(6) Hapana vulcanization inodikanwa kuchengetedza simba.Tora kushandiswa kwesimba kwepamusoro-pressure hose production semuenzaniso: 188MJ / kg yerubha uye 144MJ / kg yeTPR, iyo inogona kuchengetedza kupfuura 25% yesimba;(7) Kuzvisimbisa kwacho kwakakura, uye fomula yacho inorerutswa zvakanyanya, kuitira kuti pesvedzero yemusanganiswa wepolymer iderere zvakanyanya, uye kuita kwemhando kuri nyore kugona;(8) Inovhura nzira nyowani dzeindasitiri yerabha uye inowedzera nzvimbo yekushandisa yezvigadzirwa zverabha.Izvo zvisingabatsiri ndezvokuti kupisa kwekushisa kweTPR hakuna kunaka seyerabha, uye pfuma yemuviri inoderera zvikuru nekuwedzera kwekushisa, saka chiyero chekushandiswa chishoma.Panguva imwecheteyo, iyo compression deformation, kusimba uye kusimba kwakaderera kune iyo yerabha, uye mutengo unowanzo kukwirira kupfuura iwo werabha yakafanana.Nekudaro, kazhinji, zvakanakira TPR zvichiri kushamisa, nepo zvisizvo zviri kuramba zvichivandudza.Serudzi rutsva rwekuchengetedza simba uye nharaunda-inoshamwaridzika rabha zvinhu, TPR ine inovimbisa budiriro tarisiro.
Polyurethane (PU), iro zita rakazara ipolyurethane, inhengo yepolymer.Yakagadzirwa naOtto Bayer muna 1937. Polyurethane yakakamurwa kuva mapoka maviri: polyester type uye polyether type.Anogona kugadzirwa kuva mapurasitiki epolyurethane (kunyanya mapurasitiki ane furo), polyurethane fibers (inonzi spandex kuChina), polyurethane rubber uye elastomers.
Yakapfava polyurethane inonyanya kuve thermoplastic linear chimiro, iyo ine kugadzikana kuri nani, makemikari kuramba, kusimba uye michina zvivakwa kupfuura PVC furo zvinhu, uye ine kushoma kudzvanya deformation.Iyo ine yakanaka yekupisa yekupisa, kuvharidzira inzwi, kushomeka kuramba uye anti-virus kuita.Naizvozvo, inoshandiswa sekurongedza, kuvharidzira ruzha, sefa zvinhu.
Rigid polyurethane plastiki ine huremu huremu, yakanakisa mukudzivirira inzwi uye kupisa kwemafuta, makemikari kuramba, yakanaka magetsi emagetsi, kugadzirwa nyore, uye kunyura kwemvura.Inonyanya kushandiswa mukuvaka, mota, indasitiri yendege, thermal insulation structural zvinhu.
Kuita kwe polyurethane elastomer kuri pakati pepurasitiki nerabha, mafuta kuramba, kupfeka kuramba, kushomeka kwekushisa, kuramba kuchembera, kuoma kwakanyanya uye elasticity.Inonyanya kushandiswa muindasitiri yeshangu uye indasitiri yezvokurapa.Polyurethane inogona zvakare kushandiswa kugadzira anonamira, machira, synthetic dehwe, nezvimwe.
Polyurethane yakaonekwa muma1930s.Mushure memakore anoda kusvika makumi masere ekuvandudzwa kwetekinoroji, chinyorwa ichi chave kushandiswa zvakanyanya mumunda wemidziyo yepamba, kuvaka, zvinodiwa zvezuva nezuva, zvekufambisa, uye midziyo yemumba.
Zvakanakira: Rigid PVC ndeimwe yeanonyanya kushandiswa epurasitiki zvinhu.PVC zvinhu imhando isina crystalline zvinhu.
Mukushandiswa chaiko, PVC zvinhu zvinowanzowedzerwa nema stabilizers, lubricant, anobatsira ekugadzirisa maajenti, pigment, maagent agents uye zvimwe zvinowedzera.
PVC zvinhu hazvina kupisa, simba rakakwirira, kuramba mamiriro ekunze uye yakanakisa geometric kugadzikana.
PVC ine kuramba yakasimba kune oxidants, inoderedza maajenti uye yakasimba asidhi.Nekudaro, inogona kuve yakasvibiswa neyakaomeswa oxidizing asidhi, senge concentrated sulfuric acid uye concentrated nitric acid, uye haina kukodzera kubata anonhuwirira hydrocarbons uye chlorinated hydrocarbons.
Zvakashata: Kuyerera kwePVC maitiro asina kunaka, uye maitiro ayo akasiyana akatetepa.Kunyanya, zvinhu zvePVC zvine huremu hombe hwemamorekuru zvinonyanya kunetsa kugadzirisa (zvakadai zvinhu zvinowanzoda kuwedzera lubricant kuti uvandudze kuyerera maitiro), saka PVC zvinhu zvine huremu hudiki hwemamorekuru zvinowanzo shandiswa.
Iyo shrinkage yePVC yakanyanya kuderera, kazhinji 0, 2 - 0, 6%.
PVC iri nyore kuburitsa gasi rine muchetura mukuumbwa.
Nylon Advantage:
1. High mechanical simba, yakanaka kuoma, yakakwirira tensile uye compression simba.Iyo chaiyo yekusimba simba yakakwirira kupfuura iyo yesimbi, uye chaiyo yekumanikidza simba inofananidzwa neiyo yesimbi, asi kuomarara kwayo kushoma pane iyo yesimbi.Simba rekusimba riri pedyo nekusimba kwegoho, rinopfuura zvakapetwa kaviri kupfuura ABS.Iko kunyura kwesimba rekukanganisa uye kusagadzikana vibration kwakasimba, uye simba rekuita rakakwira zvakanyanya kupfuura iro remapurasitiki akajairwa, uye zvirinani pane aya acetal resin.
2. Kuramba kuneta kunoshamisa, uye zvikamu zvinogona kuramba zvichichengetedza simba rekutanga remagetsi mushure mekupeta kakawanda.PA inowanzoshandiswa mumamiriro ezvinhu apo nguva nenguva kuneta mhedzisiro yezvakajairwa escalator handrails uye marimu matsva ebhasikoro epurasitiki ari pachena.
3. High softening point uye heat resistance (yakadai senylon 46, high crystalline nylon ine high thermal deformation tembiricha, inogona kushandiswa kwenguva yakareba pasi pe150 ℃. Mushure megirazi fiber reinforcement, PA66 ine thermal deformation tembiricha inopfuura 250 ℃).
4. Smooth surface, duku friction coefficient, kupfeka-resistant.Inozvizora uye ine ruzha rwakaderera kana ichishandiswa sechinhu chinofambiswa chemuchina.Inogona kushandiswa pasina lubricant kana friction effect isiri yakanyanya;Kana lubricant ichidiwa chaizvo kuderedza kukwesha kana kubatsira kupisa kupisa, mvura, mafuta, girizi, nezvimwe zvinogona kusarudzwa.Naizvozvo, sechikamu chekutumira, ine hupenyu hurefu hwebasa.
5. Inopesana nekuora, alkali uye yakawanda yemunyu zvinwiwa, asidi isina simba, injini yemafuta, peturu, inonhuwira yehydrocarbon compounds uye general solvents, inert kune zvinonhuhwirira zvinonhuhwirira, asi zvisingamiri kune yakasimba acids uye oxidants.Inogona kudzivisa kukukurwa kwepeturu, mafuta, mafuta, doro, alkali isina simba, nezvimwewo uye ine simba rakanaka rekurwisa kuchembera.Inogona kushandiswa sekutakura zvinhu zvekuzora mafuta, mafuta, nezvimwe.
Zvakaipa:
1. Kunyura kwemvura kwakashata uye kugadzikana kwedimensional.
2. Kusagadzikana kunopesana nekushisa kwakadzika.
3. Iyo antistatic pfuma yakashata.
4. Kusagadzikana kwekupisa.
