I-TPR ineenzuzo ezilandelayo: (1) Iyakwazi ukucutshungulwa ngoomatshini bokubumba be-thermoplastic ngokubanzi, njengokubunjwa kwe-injection, i-extrusion molding, i-blow molding, i-compression molding, kunye ne-mold transfer transfer;(2) Inokuthi ihlanjululwe ngomatshini wokubumba inaliti yerabha, kwaye ixesha lingacuthwa ukusuka malunga ne-20min ukuya ngaphantsi kwe-1min;3(4) Inkunkuma eveliswa kwinkqubo yokuvelisa (i-burrs ebalekayo kunye nerabha ekhupha inkunkuma) kunye nemveliso yenkunkuma yokugqibela inokubuyiswa ngokuthe ngqo ukuze isetyenziswe kwakhona: (5) Iimveliso ezindala zeTPR ezisetyenzisiweyo zinokuphinda zisetyenziswe kwakhona kwaye ziphinde zisetyenziswe ukunciphisa ukungcoliseka kwendalo kunye nokwandisa. umthombo wokuhlaziywa kobutyebi;(6) Akukho vulcanization efunekayo ukugcina amandla.Thatha ukusetyenziswa kwamandla kwimveliso ye-hose ephezulu njengomzekelo: 188MJ / kg yerubha kunye ne-144MJ / kg ye-TPR, enokugcina ngaphezu kwe-25% yamandla;7(8) Ivula iindlela ezintsha zeshishini lerabha kwaye yandise indawo yokusetyenziswa kweemveliso zerabha.Ukungalungi kukuba ukuchasana nobushushu be-TPR akulunganga njengerabha, kwaye ipropati yomzimba iyancipha kakhulu ngokunyuka kweqondo lokushisa, ngoko ke ububanzi besicelo bulinganiselwe.Ngelo xesha, i-deformation deformation, ukuqina kunye nokuqina kungaphantsi kwerabha, kwaye ixabiso lihlala liphezulu kunelo lerubha efanayo.Nangona kunjalo, ngokubanzi, izibonelelo ze-TPR zisabalasele, ngelixa izinto ezingalunganga zihlala ziphucula.Njengohlobo olutsha lokonga amandla kunye nerubha ehambelana nokusingqongileyo, i-TPR inethemba lophuhliso oluthembisayo.
I-Polyurethane (PU), igama elipheleleyo yi-polyurethane, i-polymer compound.Yenziwe ngu-Otto Bayer ngowe-1937.Zingenziwa kwiiplastiki ze-polyurethane (ingakumbi iiplastiki ezinogwebu), iifiber ze-polyurethane (ezibizwa ngokuba yi-spandex e-China), i-polyurethane rubbers kunye ne-elastomers.
I-polyurethane ethambileyo ubukhulu becala sisakhiwo somgca we-thermoplastic, esinozinzo olungcono, ukuxhathisa iikhemikhali, ukomelela kunye neempawu zoomatshini kunezixhobo zogwebu zePVC, kwaye ine-deformation encinci yoxinzelelo.Ine-insulation efanelekileyo ye-thermal, ukugquma kwesandi, ukuxhathisa ukothuka kunye nokusebenza kwe-anti-virus.Ke ngoko, isetyenziselwa ukupakisha, ukugquma isandi, izixhobo zokucoca.
Iplastiki ye-polyurethane eqinile ilula ngobunzima, igqwesileyo kwi-insulation yesandi kunye nokufakwa kwe-thermal, ukuxhathisa imichiza, iimpawu zombane ezilungileyo, ukusetyenzwa lula, kunye nokufunxa kwamanzi aphantsi.Isetyenziswa ikakhulu kulwakhiwo, iimoto, ishishini lokuhamba ngenqwelomoya, izixhobo zokugquma i-thermal.
Ukusebenza kwe-polyurethane elastomer kuphakathi kweplastiki kunye nerabha, ukuxhathisa kweoli, ukuxhathisa ukunxiba, ukumelana nobushushu obuphantsi, ukumelana nokuguga, ubunzima obuphezulu kunye nokuqina.Isetyenziswa kakhulu kwishishini leembadada nakwishishini lezonyango.I-polyurethane ingasetyenziselwa ukwenza izinto zokuncamathelisa, iingubo, isikhumba sokwenziwa, njl.
Ipolyurethane yavela kwi-1930s.Emva kweminyaka ephantse ibe yi-80 yophuhliso lwetekhnoloji, olu lwazi luye lwasetyenziswa ngokubanzi kwinkalo yefenitshala yasekhaya, ulwakhiwo, iimfuno zemihla ngemihla, ezothutho, kunye nezixhobo zasekhaya.
Izinto eziluncedo: I-PVC engqongqo yenye yezona zinto zisetyenziswa kakhulu kwiplastiki.PVC izinto luhlobo lwemathiriyeli non crystalline.
Ekusetyenzisweni okwenyani, izinto zePVC zihlala zongezwa kunye nezinzisi, izithambiso, iiarhente ezincedisayo, ii-pigments, ii-agent zempembelelo kunye nezinye izongezo.
Izinto zePVC zinokutsha, ukomelela okuphezulu, ukumelana nemozulu kunye nokuzinza okuhle kakhulu kwejometri.
I-PVC inokumelana okunamandla kwii-oxidants, ii-agent zokunciphisa kunye nee-acids ezinamandla.Nangona kunjalo, inokugqweswa yi-acids egxininisiweyo ye-oxidizing, efana ne-sulfuric acid egxininisiweyo kunye ne-nitric acid, kwaye ayifanelekanga ukuqhagamshelana nee-hydrocarbons ezinevumba elimnandi kunye ne-chlorinated hydrocarbons.
Ukungalungi: Iimpawu zokuhamba kwePVC zimbi kakhulu, kwaye uluhlu lwenkqubo yalo lumxinwa kakhulu.Ngokukodwa, izinto zePVC ezinobunzima obukhulu bemolekyuli zinzima ngakumbi ukusetyenzwa (izinto ezinjalo zihlala zifuna ukongeza i-lubricant ukuphucula iimpawu zokuhamba), ngoko ke izixhobo zePVC ezinobunzima obuncinci bemolekyuli zihlala zisetyenziswa.
Ukuncipha kwePVC kuphantsi kakhulu, ngokubanzi 0, 2 - 0, 6%.
I-PVC kulula ukukhulula igesi eyityhefu kwinkqubo yokubumba.
Inzuzo yenayiloni:
1. Amandla omatshini aphezulu, ukuqina okuhle, ukunyanzeliswa okuphezulu kunye namandla oxinzelelo.Amandla athile okuqina angaphezulu kwalawo esinyithi, kwaye amandla athile oxinzelelo afaniswa nentsimbi, kodwa ukuqina kwayo kungaphantsi kokwentsimbi.Amandla e-tensile asondele kumandla esivuno, ngaphezu kokuphindwe kabini ukuphakama kwe-ABS.Umthamo wokufunxa wempembelelo kunye noxinzelelo lwe-vibration yomelele, kwaye amandla empembelelo aphezulu kakhulu kuneeplastiki eziqhelekileyo, kwaye angcono kune-acetal resin.
2. Ukumelana nokukhathala kubalaseleyo, kwaye iinxalenye zisenako ukugcina amandla omatshini wokuqala emva kokugoba ngokuphindaphindiweyo.I-PA isoloko isetyenziswa kwiimeko apho isiphumo sokudinwa rhoqo kwee-handrails eziqhelekileyo ezizihambelayo kunye neerim zebhayisekile zeplastiki ezintsha zicace kakhulu.
3. Iqondo eliphezulu lokuthambisa kunye nokumelana nobushushu (njenge-nylon 46, i-nylon ephezulu ye-crystalline ine-thermal deformation yeqondo lokushisa, elingasetyenziselwa ixesha elide phantsi kwe-150 ℃. Emva kokuqiniswa kwe-glass fiber, i-PA66 ine-thermal deformation yeqondo lokushisa elingaphezulu kwe-thermal deformation. 250 ℃).
4. Umphezulu ogudileyo, i-coefficient encinci ye-friction, i-wear-resistant-resistant.Iyazithambisa kwaye inengxolo ephantsi xa isetyenziswa njengomatshini oshukumayo.Ingasetyenziswa ngaphandle kwe-lubricant xa umphumo wokukhuhlana awuphezulu kakhulu;Ukuba i-lubricant iyadingeka ngokwenene ukunciphisa ukukhuhlana okanye ukunceda ukutshatyalaliswa kobushushu, amanzi, ioli, igrisi, njl.Ke ngoko, njengecandelo losulelo, inobomi obude benkonzo.
5. Iyakwazi ukumelana ne-corrosion, i-alkali kunye ne-alkali eninzi yetyuwa, i-asidi ebuthakathaka, i-oyile ye-injini, i-petroli, i-aromatics hydrocarbon compounds kunye ne-solvents jikelele, i-inert kwi-aromatics compounds, kodwa ayinakumelana ne-acids eqinile kunye ne-oxidants.Iyakwazi ukuxhathisa ukukhukuliseka kwepetroli, ioli, amafutha, utywala, i-alkali ebuthathaka, njl. kwaye inamandla okuthintela ukuguga.Ingasetyenziselwa njengento yokupakisha ioli yokuthambisa, i-fuel, njl.
Izinto ezingeloncedo:
1. Ukufunxwa kakuhle kwamanzi kunye nokuzinza kwe-dimensional.
2. Ukuchasana kakubi kwiqondo lokushisa eliphantsi.
3. Ipropathi ye-antistatic imbi.
4. Ukumelana nobushushu obuphantsi.
