Munzvimbo inokurumidza kubuda yepolymer processing, thermoplastic elastomers (TPEs) dzakabuda sekirasi inosiyana-siyana uye inokosha yezvishandiso, kuvhara mukaha uripo pakati pemapurasitiki akaomarara uye elastic rubber. Musanganiswa wavo wakasarudzika we thermoplastic processability uye elastomeric kuchinjika kwakavaita zvinhu zvesarudzo pane akasiyana maindasitiri., kubva kumotokari uye zvemagetsi kusvika pakuvaka uye zvinhu zvevatengi. Zhuoyue, mutungamiri mune extrusion tekinoroji, yakatsaurirwa kupa nyika-ye-iyo-inotenderera inotenderera yakafanana mapatya-screw extruders yakanyatsogadzirirwa kusanganisa uye kugadzirisa maTPEs., kusanganisira TPE/SBS/TPU/TPR/TPV uye mamwe makombiji ane hukama. Nekunzwisisa kwakadzama kweTPE zvinhu zvivakwa uye indasitiri yekushandisa zvinodiwa, Zhuoyue's extruder series inopa kushanda kusingaenzaniswi, kunyatsoshanda, uye kuvimbika, kupa vagadziri simba rekuvhura kugona kwakazara kwezvinhu izvi zvepamberi.

1. Mhedziso yeThermoplastic Elastomers (TPEs)

Thermoplastic Elastomers (TPEs), dzimwe nguva inonzi Thermoplastic Rubbers (TPRs), imhuri dzakasiyana dzemidziyo inoratidza huviri hunhu hwe thermoplastics uye elastomers. Kusiyana netsika dzakasungirirwa rubbers, izvo zvisingagoneki uye zvisinganyungudika kana zvangorapwa, MaTPE anogona kunyungudutswa uye kudzokororwa uchishandisa yakajairwa thermoplastic kugadzirisa nzira senge extrusion, jekiseni kuumba, uye kuumbwa kwemhepo, uku uchichengetedza yakanakisa elastic kupora uye kuchinjika pane tembiricha yekamuri. Uhu hunyambiri hwakasiyana uhwu hunobva pakuumbwa kwavo kwemamorekuru: TPEs anowanzo kunge ari copolymers (mapolymer anoumbwa maviri kana anopfuura akasiyana monomer unit) kana kusanganiswa kwemuviri kwechikamu chepurasitiki uye chikamu cherubha, uko chikamu chepurasitiki chinoumba matrix inoenderera inonyorovesa uye inoyerera kana ichipisa, uye chikamu cherabha chinopa elasticity uye kusimba.

Mabhenefiti akakosha eTPEs pamusoro peakajairwa marabha uye mapurasitiki akatungamira kutorwa kwavo kwakapararira mukugadzira kwemazuva ano.. Zvakanakira izvi zvinosanganisira: yakanakisa processability (kubvumira kugadzirwa kwepamusoro-soro uye yakaoma chikamu geometries), recyclability (kuderedza tsvina yezvinhu uye kukanganisa kwezvakatipoteredza), yakanaka makemikari kuramba, yepamusoro michina zvinhu (zvakadai sekusimba kwesimba, elongation panguva yekuzorora, uye kuramba abrasion), uye kugona kuve neruvara, textured, kana kugadziridzwa kuti isangane nezvinodiwa zvekushandisa. Uyezve, MaTPE anopa mari yekuchengetedza mukugadzira nekuda kwenguva pfupi yekutenderera, kuderedza kushandiswa kwesimba, uye kubviswa kwekurapa matanho anodiwa kune echinyakare rabha.

Sekuda kwekureruka, yakasimba, uye zvinhu zvakagadzikana zvinoramba zvichikura, MaTPE ave kuwedzera kukosha mumaindasitiri akadai semotokari (kuitira kureruka uye kuderedza ruzha), zvemagetsi (nokuda kwezvikamu zvinoshanduka uye zvakasimba), uye zvinhu zvevatengi (kune zvakagadzika uye ergonomic zvigadzirwa). Kukwirisa zvizere mabhenefiti eTPEs, vagadziri vanoda michina yekugadzirisa iyo inogona kubata yakasarudzika matambudziko ezvigadzirwa izvi, kusanganisira kunzwa kwavo kune tembiricha, shear rate, uye kusanganisa kufanana. Zhuoyue's co-inotenderera parallel mapatya-screw extruders akagadzirirwa kugadzirisa matambudziko aya., kuve nechokwadi kuenderana, yepamusoro-soro TPE maumbirwo ane optimal performance.
