zvigadzirwa

Mumakore achangopfuura, zvinhu zvisinganyanyi kureruka, zvine kabhoni shoma, uye zvine simba rakawanda zvave zvinhu zvikuru zvitatu zveindasitiri yekugadzira. Kunyangwe zvinhu zvesimbi zvechinyakare zvine simba rakawanda, zvine simba rakawanda, zvinoshandisa simba rakawanda pakugadzira, uye zvinogona kuonda; Kunyangwe mapurasitiki akajairwa egirazi mapfupi akasimbiswa nefiber anoderedza huremu zvakanyanya, anowanzoita zvisina kunaka kana achitakura kwenguva refu, achichinja tembiricha yepamusoro neyakaderera, uye ane madziro matete ane simba rakawanda. Ndiko kuti girazi refu rakasimbiswa polypropylene (LGF-PP) uye girazi refu rakasimbiswa polyamide (LGF-PA66) zvinoonekwa seimwe yemhando dziri kukura nekukurumidza mumunda wepurasitiki dzakagadziriswa pasi rose.

Zvimwe, Mabhenefiti makuru e tekinoroji ekushandisa zvinhu zvegirazi refu zvakasimbiswa nefiber

Kusiyana nemapurasitiki mapfupi akasimbiswa nefiber yegirazi (ane urefu hwefiber hunowanzova pakati pe0.2 kusvika 0.6mm), zvinhu zvegirazi refu zvakasimbiswa nefiber zvinochengetedza hurefu hwe10-25mm mu resin matrix kuburikidza nemaitiro akakosha ekuisa impregnation uye extrusion, uye zvinoumba chimiro che network chine mativi matatu mushure mekuumbwa kwejekiseni.

Chimiro ichi chinounza matanho matatu akakosha ekuvandudza mashandiro:

1. Kudzivirira kwakanyanya kwesimba

Network refu yegirazi inogona kudzivirira kupararira kwematombo, uye simba rema "notch impact" rakakwirira ne40-80% kupfuura re "short fiber PP/PA". Patembiricha yakaderera ye -40 ℃, zvinhu zvakajairika zvinogona kutyoka, nepo zvinhu zvegirazi refu zvinogona kuchengetedza anopfuura 80% yekushanda kwazvo kwekupisa kwemukamuri.

2. Kuramba kwakanaka kwazvo uye kugadzikana kwakaenzana

Kana zvinhu zvikasamira zvakanaka kwenguva refu (sezvakaita mafuremu emukati memotokari netsoka dzemidziyo yepamba), zvinhu zvemafaibha mapfupi zvichashanduka zvakanyanya, nepo zvinhu zvemafaibha marefu zvichaderedzwa neanopfuura 50% nekuda kwekutsigira kwefuremu yefaibha. Panguva iyi, mukuyedzwa kwekupisa kwakanyanya uye kwakaderera pakati pe -40 ℃ ne 120 ℃, kushanduka kwewarpage kwezvigadzirwa zvefaibha marefu zvegirazi kunongova chikamu chimwe muzvitatu chefaibha mapfupi.

3. Simba guru uye rakareruka

Kuwanda kwesimbi iyi kunongova 1/2 ~ 1/3 yesimbi dzearuminiyamu (LGF-PP inenge 1.0 ~ 1.2 g/cm³, LGF-PA66 inenge 1.3 ~ 1.5 g/cm³), asi simba rayo (simba/kuwanda) riri pedyo kana kutopfuura mamwe simbi dzearuminiyamu, zvichiita kuti ive sarudzo yakanaka ye "kutsiva simbi nepurasitiki".

二、 Nzvimbo dzakajairika dzekushandisa uye zvinodiwa zvavo zvezvinhu

Zvimwe, Ruzivo rweMaitiro eMusika

Zvichienderana nehuwandu hwevamwe, musika wepasi rose wezvinhu zvakagadzirwa negirazi refu zvakasimbiswa nefiber zvinogadzirwa nethermoplastic zvinotarisirwa kusvika mabhiriyoni maviri nehafu emadhora ekuAmerica muna 2023 uye zvinotarisirwa kusvika mabhiriyoni mana nehafu emadhora ekuAmerica panosvika 2030, nekukura kwegore negore kwe7.2%. Pakati pavo, dunhu reAsia Pacific ndiro rine kukura nekukurumidza, uye China, semugadziri mukuru uye mutengesi wepurasitiki dzakagadziriswa, iri kutsiva zvishoma nezvishoma zvinhu zvakagadzirwa nemitengo yakakwira kubva kuEurope neAmerica.

四、 Mamiriro edu

Kambani yedu yave ichinyanya kutarisa pakutsvaga nekugadzira LGF-PP neLGF-PA66 kwemakore anopfuura makumi maviri, iine kodzero dzakazvimirira dzepfuma yepfungwa dzekushandisa tekinoroji yekupinda fiber kwenguva refu. Zvigadzirwa zvedu zvakatumirwa zvakawanda kuEurope, Russia, Southeast Asia, Middle East, South America nedzimwe nzvimbo. Hatingope magiredhi akajairwa chete, asi tinogadzirisawo mafomura zvichienderana nenzvimbo dzekushandiswa kwevatengi (tembiricha yepamusoro neyakaderera, hunyoro, mavara emafuta, kuratidzwa kwekunze), zvichibatsira vatengi kuderedza zvakanyanya mitengo yezvinhu uku vachiona kushanda zvakanaka.
