Solvent-based Tpu anomhan'arira yakanaka viscosity
About TPU
TPU (iyo thermoplastic polyurethanes) inovhara iyo midziyo yepakati pakati pemarara nemapurasitiki. Yayo mhando yezvivakwa zvemuviri inogonesa TPU kuti ishandiswe seyakaomeswa rabar uye yakakurumbira muzviuru zvezvigadzirwa, nekuda kwekureba kwavo, kupfava uye kupfava pakati pezvimwe zvakanaka. Mukuwedzera, ivo vari nyore kugadzirisa.
Semunhu anobuda-stept-tech uye ane hushamwari zvinhu, Tpu ane zvakawanda zvakanakisa zvivakwa zvakakura, kushomeka kwakatanhamara, kuita kwoushamwari, kuramba zvakanaka, kuramba kwemvura, kupokana kwemvura uye kudzikama kwemvura.
Application
Zvishandiso: solvent madekisheni, inopisa-nyungudutsa ashesive mafirimu, shangu inonamatira.

Kubata uye kuchengetedza
1. Ngwarira kufema thermal kugadzirisa mafuru uye vapar
2. Michina yekubata michina inogona kukonzera kuumbwa kweguruva. Ngwarira guruva rekufema.
3. Shandisa nzira dzakakodzera dzinogara paunenge uchibata chigadzirwa ichi kudzivirira magetsi ekubhadhara
4. Pellets pasi pasi inogona kunge ichitsvedza uye kukonzera kudonha
Kuchengetedza mazano: kuchengetedza zvigadzirwa zvemhando yepamusoro, chengetedza chigadzirwa munzvimbo inotonhorera, yakaoma. Chengetedza mumudziyo wakasungwa wakasungwa.
Zvinyorwa
1. Yakashata TPU zvigadzirwa hazvigone kushandiswa kugadzirisa zvigadzirwa.
2. Pamberi pekuumbwa, kunyanya panguva yekuumbwa, nekurova kuumbwa, uye mafirimu achivhima, nezvinodiwa zvekunyorova zvemoyo unyoro, kunyanya mumwaka wakanyorova uye nzvimbo dzakanyorova.
3. Munguva yekugadzira, chimiro, compresmed ratio, groove yakadzika, uye chimiro chichiitika l / d yeiyo screw inofanira kutariswa zvichienderana nehunhu hwezvinyorwa zvezvinyorwa. Injection inoumba screws inoshandiswa jekiseni kuumbwa, uye kuendesa zviyero zvinoshandiswa kuumbwa.
