Polyether mhando TPU-M series/ Polycarbonate granules/Plastic raw material/Tpu plastic raw material mutengo
nezve TPU
Thermoplastic polyurethane elastomer (TPU) imhando ye elastomer inogona kugadzirwa nepurasitiki nekudziya nekunyungudutswa ne solvent. Ine hunhu hwakanaka hwakaita sesimba guru, kusimba kwakanyanya, kuramba kupfeka uye kuramba mafuta. Ine mashandiro akanaka ekugadzirisa uye inoshandiswa zvakanyanya mukudzivirira kwenyika, kurapa, chikafu nemamwe maindasitiri. Thermoplastic Polyurethane ine mhando mbiri: polyester mhando ne polyether mhando, chena random spherical kana columnar particles, uye density i 1.10 ~ 1.25g / cm3. Huwandu hwe polyether mhando hudiki pane hwe polyester mhando. Tembiricha yekuchinja kwegirazi ye polyether mhando i 100.6 ~ 106.1 ℃, uye tembiricha yekuchinja kwegirazi ye polyester mhando i 108.9 ~ 122.8 ℃. Tembiricha ye brittleness ye polyether mhando ne polyester mhando yakaderera pane -62 ℃, uye kuramba tembiricha yakaderera ye polyether mhando kuri nani pane kwe polyester mhando. Zvinhu zvinoshamisa zve polyurethane thermoplastic elastomers ndezvekuti inodzivirira kupfeka zvakanaka, inodzivirira ozone zvakanyanya, yakaomarara, ine simba rakawanda, inochinjika zvakanaka, inodzivirira tembiricha yakaderera, inodzivirira mafuta zvakanaka, inodzivirira makemikari uye inodzivirira zvakatipoteredza. Kugadzikana kwehydrolytic kwerudzi rwe ester kwakakwira zvakanyanya kupfuura kwerudzi rwe polyester.

Makoshero ari pamusoro apa anoratidzwa semakoshero akajairika uye haafanirwe kushandiswa semarongero.
Pasuru
25KG/bhegi, 1000KG/pallet kana 1500KG/pallet, pallet yepurasitiki yakagadziriswa
Kubata uye Kuchengeta
1. Dzivisa kufema utsi nemafuta anoshandiswa pakupisa
2. Midziyo yekubata nemidziyo inogona kukonzera guruva. Dzivisa kufema guruva.
3. Shandisa nzira dzakakodzera dzekuisa pasi pakubata chigadzirwa ichi kudzivirira kushaikwa kwemagetsi
4. Matumbu ari pasi anogona kunge achitsvedza uye achikonzera kudonha
Zvinokurudzirwa pakuchengeta: Kuti chigadzirwa chirambe chakanaka, chengetai chigadzirwa munzvimbo inotonhorera uye yakaoma. Chengetai mumudziyo wakavharwa zvakasimba.
