1. Huremu

Purasitiki chinhu chakareruka chine hukama hwe 0.90-2.2.Zviripachena, mapurasitiki anogona kuyangarara pamusoro pemvura here?Kunyanya mapurasitiki ane furo, nekuda kweiyo micropores mukati, magadzirirwo acho akareruka, uye huwandu hwehukama hunongova 0.01.Iyi ficha inobvumira mapurasitiki kuti ashandiswe mukugadzira zvigadzirwa zvinoda kurerutswa kwehuremu hwazvo.

2. Yakanakisa kugadzikana kwemakemikari

Mapurasitiki mazhinji ane kunaka kwekusagadzikana kumakemikari akadai seasidhi uye alkali.Kunyanya, polytetrafluoroethylene (F4), inowanzozivikanwa seMambo wePlastiki, inonyanya kugadzikana mumakemikari kupfuura goridhe, uye haizoparari kunyange kana yakabikwa mu "aqua regia" kwemaawa anopfuura gumi.Nekuti F4 ine yakanakisa kugadzikana kwemakemikari, chinhu chakanakira corrosion-resistant material.Semuyenzaniso, F4 inogona kushandiswa sechinhu kutakura zvinoparadza uye viscous liquid pombi.

3. Yakanakisa magetsi ekudzivirira zvinhu

Mapurasitiki akajairwa akashata maconductor emagetsi, uye kuramba kwavo kwepamusoro uye vhoriyamu kuramba yakakura kwazvo, inogona kusvika 109 kusvika 1018 ohms muhuwandu.Iyo yekuputsa voltage yakakura, uye iyo dielectric kurasikirwa tangent kukosha idiki.Naizvozvo, mapurasitiki ane huwandu hwakasiyana hwekushandisa muindasitiri yemagetsi uye indasitiri yemichina.Zvakadai sepurasitiki insulated control cables.

4. Yakashata thermal conductor, ine kuderedzwa kweruzha uye kuvhunduka kubatwa

Kazhinji kutaura, kupisa kwekupisa kwepurasitiki kwakadzikira, zvakaenzana ne1/75-1/225 yesimbi, uye mamicropores epurasitiki yefuro.

Iine gasi, iyo ine zviri nani kupisa kupisa, kuvharidzira inzwi uye kushomeka kuramba.Semuenzaniso, thermal conductivity ye polyvinyl chloride (PVC) inongova 1/357 yesimbi uye 1/1250 yealuminium.Panyaya yekupisa kwekupisa, mahwindo epurasitiki egirazi rimwe chete akakwira ne40% kupfuura mahwindo ealuminium egirazi rimwe chete, uye mahwindo emagirazi maviri akakwira 50%.Mushure mokunge hwindo repurasitiki rasanganiswa negirazi risina girazi, rinogona kushandiswa munzvimbo dzekugara, zvivako zvehofisi, mawadhi, uye mahotera, kuchengetedza kupisa munguva yechando uye kuchengetedza mari yemhepo yemhepo muzhizha, uye zvikomborero zviri pachena.

5. Kupararira kwakakura kwesimba remagetsi uye yakakwirira chaiyo simba

Mamwe mapurasitiki akaoma sedombo nesimbi, uye mamwe akapfava sepepa nedehwe.Kubva pamaonero ezvivakwa zvemuchina senge kuoma, kusimba kwesimba, kurebesa, uye kusimba kwesimba remapurasitiki, ane hupamhi hwekuparadzira uye ane akawanda sarudzo dzekushandisa.Nekuda kweiyo diki chaiyo giravhiti uye yakakwirira simba repurasitiki, ine yakakwirira chaiyo simba.Zvichienzaniswa nezvimwe zvinhu, mapurasitiki anewo zvikanganiso zviri pachena, sekupisa, kuomarara kwepamusoro pane simbi, kusakara kuchembera, uye kupisa kupisa.

Nokudaro, zvigadzirwa zvedu zvepurasitiki zvinoshandisa zvinhu zvepurasitiki maererano nemhando yechigadzirwa
Semuyenzaniso:chipunuzvigadzirwa zvinonyanya giredhi rekudya PP uye yekurapa giredhi PP.
Thesirinjiigiredhi rekurapa PP, uye iyotest tubeane giredhi rekurapa PP kana PS.Thespray bottleinongova musanganiswa wePET uye PP.

Nokutimouldzvinhu zvatinoshandisa zvakanaka kwazvo mold steel, zvakadai se 718. Unhu hwezvigadzirwa zvepurasitiki zvakagadzirwa zvakanaka kwazvo.Tine makore gumi nematatu echiitiko chenhoroondo munzvimbo ino, nyanzvi
