Isikhokelo sePlasikisi yokhetho

Kumashishini ahlukeneyo, iinxalenye zeplastiki zisetyenziswa ngakumbi kwaye ngaphezulu kokutshintsha izinyithi ezinje ngobhedu, intsimbi engenasigaba, ialuminiyam kunye ne-ceramics. Izizathu zokuthandwa kweeplastiki, ezinje:

Kule mihla, zininzi iintlobo zeplastiki, kwaye kubaluleke kakhulu ukukhetha iplastiki efanelekileyo. Ezi zikhokelo zilandelayo zinokukunceda ukomeleze ukuqhelana kwakho neemveliso zeplastiki kwaye kufezekise ukhetho lwezinto ezingcono.

1. Chonga umsebenzi wecandelo olifunayo.
Kwizicelo zeflethi kunye nezixhobo ze-crystalline (i-nylon, i-polyoxymethylene) zingcono kunezinto ze-amorsulfone (ezinjenge-polysulfone, peli okanye i-polycarbonate).
Intsebenzo ye-factions inokuphuculwa yi-molybdenum
Intsebenzo yesakhiwo inokuphuculwa kukuqinisa imicu, njengeglasi okanye ikhabhoni.
Nje ukuba uthathe isigqibo malunga nomsebenzi wecandelo (ukugcwala okanye ulwakhiwo), unokukodwa ngakumbi kukhetho ngokumisela iimfuno zempawu zobuchwephesha. Ngokuphathelele kunye nezicelo zefreyiti, eyona nto iphambili ekuqwalaselweni kwendlela, kwaye iiparamitha ezinomdla ziyixabiso le-PV kwaye "k". Bala ixabiso elifunekayo le-PV (uxinzelelo (i-PSI) x isantya (m / min)). Khetha umxholo oxabiso layo le-PV lingaphezulu kwexabiso lokubala; Emva koko, ukunciphisa uluhlu lwezinto ezibonakalayo ngokwendlela "k" inxibe into. Ngokubanzi, ezantsi kwe "k", icotha impahla eqingqiweyo kunye nobude ubomi.
Olona xinzelelo luphezulu lokusebenza kwamacandelo olwakhiwo kubushushu obuthile lwenzelwe ukuba ngama-25% amandla awo aphezulu.

2. Cinga ngeemfuno zobushushu zamacandelo avela kuzo zombini iimeko kunye neemeko ezigqithisileyo.
Ukuxhathisa ubushushu kwento ebonakalayo ichazwa bubushushu obushushu bokulahla ubushushu (i-HDT) kunye neqondo lobushushu eliqhubekayo. I-HDT sisibonisi seqondo lobushushu elibonakalayo, isetyenziswa ngokubanzi njengeyona nyama iqondo liphezulu phantsi koxinzelelo oluphakathi kunye nophezulu. Iqondo lobushushu eliqhubekayo libhekisa ekubonakaleni kwexesha elide ngaphezulu kobushushu, iipropathi zomzimba zezinto eziza kubakho zibalulekileyo kwaye zisisigxina.
Inqaku lokunyibilika kwezixhobo zekristali kunye neqondo lokushisa leglasi ye-amorphous Izixhobo ze-amorphous yimida yobushushu yexesha elifutshane enokugcina i-morphology endedwa. Uninzi lweemveliso zeplastiki zobunjineli kufuneka zisebenze ngezantsi kobushushu, kuba i-polymer iya kuphulukana neempawu zayo zoomatshini kweli xesha lobushushu.

3. Cinga ngeekhemikhali ezisetyenzisiweyo xa zisetyenziswa izixhobo kwaye zicocwe.
Cinga ukuba uxinzelelo, ubushushu, ixesha kunye noxinzelelo zizinto zonke ezichaphazela ukufaneleka kwento leyo. I-NYLOLO, iPolyoxyythynene kunye ne-Pet-P zihlala zilungele indawo yezomsebenzi. I-Crystalline Izixhobo eziphezulu eziphezulu ezifana nokuqiniswa kwe-PTFE, i-PPS kunye ne-peek ilungele ukusetyenziswa kwiindawo ezinobuso obuqhetseba kakhulu. Kucetyiswa ngamandla ukuba wenze uvavanyo phantsi kweemeko zokusebenzisa.

4. Ezinye iimpawu zezixhobo kufuneka ziqwalaselwe xa ukhetha izixhobo, kubandakanya:
Ukunganyangeki kwempembelelo, ukuqina, uzinzo oluhle, ukuthotyelwa kwemigaqo yearhente yolawulo. Izinto ezinama-elongwation ephezulu, amandla empembelelo kunye namandla amanxuwa zihlala zinamandla ngokubanzi kwaye azithobeli i-notches.

5. Chonga amandla okuphucula izinto ezikhethiweyo.
Ubuchule boomatshini buyinto ekhuthazayo yokukhethwa kwezinto. Khetha izixhobo zokukhulula uxinzelelo ukuphucula amandla omatshini. Ngokubanzi, iiglasi kunye neemveliso zekharbon eziqinileyo zinovelwano ngakumbi kwi-firings yesixhobo kunye nee-nosches ngexesha lemveliso enokusetyenziswa. Iimveliso eziphuculweyo zihlala zizinza ngakumbi ngexesha lematshini.
Ngenxa yobunzima babo obukhulu kakhulu, izixhobo zebhayisekile (ezinje nge-PAI, i-PI kunye ne-PI) ziya kuba ngumngeni kakhulu kwinkqubo. Kwinkqubo yoomatshini kwezi zixhobo, izixhobo ze-carbide ze-carbide kunye nezixhobo ze-polycrystalline zedayimani kufuneka zisetyenziswe.

6. Khetha eyona profayili esebenzayo:
Nceda uqiniseke ukuba ufundele yonke iprofayili enokwenzeka-fumana eyona profayili yezoqoqosho ukuze kuncitshiswe iindleko.
