imikhiqizo

Eminyakeni yamuva nje, izinto ezilula, ezinekhabhoni ephansi, kanye nokusebenza okuphezulu kube yizihloko ezintathu eziyinhloko embonini yokukhiqiza. Nakuba izinto zensimbi zendabuko zinamandla aphezulu, zinobuningi obukhulu, ukusetshenziswa kwamandla okuphezulu kokucubungula, futhi zithambekele ekugqwaleni; Nakuba amapulasitiki avamile aqiniswe ngefayibha yengilazi emfushane anemiphumela ebalulekile yokunciphisa isisindo, awenzi kahle ngaphansi kwezidingo ezifana nomthamo wokuthwala umthwalo wesikhathi eside, amazinga okushisa aphezulu naphansi ashintshashintshayo, kanye nokuqina okuphezulu okunezindonga ezincane.

Kukulesi simo lapho i-polypropylene eqiniswe ngefayibha ende (LGF-PP) kanye ne-polyamide eqiniswe ngefayibha ende (LGF-PA66) zivelele njengenye yezigaba ezikhula ngokushesha kakhulu emkhakheni wepulasitiki oguquliwe emhlabeni jikelele. Ngokwezibalo zemboni, usayizi wemakethe yomhlaba wonke we-long glass fiber eqiniswe ngefayibha ende kulindeleke ukuthi ukhule kusukela cishe kumadola aseMelika ayizigidi eziyizinkulungwane ezingu-2.8 ngo-2023 kuya kumadola aseMelika ayizigidi eziyizinkulungwane ezingu-4.5 ngo-2030, ngesilinganiso sokukhula sonyaka esihlanganisiwe esingaba ngu-7.2%, ikakhulukazi esiqhutshwa yimithetho elula kanye nezingcindezi zezindleko.

一,Izinzuzo zobuchwepheshe eziyinhloko zezinto eziqiniswe ngefayibha yengilazi ende

Ngokungafani namapulasitiki amafushane aqiniswe ngefayibha yengilazi (ngokuvamile ubude obungu-0.2-0.6mm), izinto ezinde eziqiniswe ngefayibha yengilazi zigcina ubude befayibha yengilazi obungu-10-25mm ku-resin matrix ngezinqubo ezikhethekile zokufaka nokukhipha, futhi zakha isakhiwo senethiwekhi esinezinhlangothi ezintathu ngemva kokubumba ngomjovo. Kufanele kuqashelwe ukuthi izinga lokugcina lesi sakhiwo senethiwekhi lincike ekwakhiweni kwesikulufo kanye nesimo sesango ngesikhathi sokubumba ngomjovo; Uma inqubo ingafanele, ubude be-fiberglass bungase bunciphe kakhulu.

Lesi sakhiwo siletha ukuthuthukiswa kokusebenza okuthathu okubalulekile:

1. Ukumelana nomthelela omkhulu kakhulu

Inethiwekhi yefayibha yengilazi ende ingavimbela ngempumelelo ukusabalala kwemifantu, futhi amandla ayo okushaya kwe-notch aphezulu ngo-40% -80% kunalawo efayibha emfushane i-PP/PA. Ezingeni lokushisa eliphansi elingu--40 ℃, izinto ezivamile zithambekele ekuqhekekeni, kuyilapho izinto zefayibha yengilazi ende zisengagcina ukusebenza kwazo kokushaya kwe-80% ekushiseni kwegumbi. Idatha engenhla isekelwe ezindinganisweni zokuhlola ze-ISO 179 noma i-ASTM D256.

2. Ukumelana okuhle kakhulu kokunyenya kanye nokuqina okulinganayo

Ngaphansi kwemithwalo yesikhathi eside engaguquki (njengezinhlaka zezimoto kanye nemilenze yokusekela izinto zasekhaya), izinto zefayibha ezimfushane zizobhekana nokuguquguquka okukhulu kokuqhekeka, kuyilapho izinto zefayibha yengilazi ende zizoncishiswa izinga lokuqhekeka ngaphezu kuka-50% ngenxa yokusekelwa kwethambo lefayibha yengilazi. Okwamanje, ekuhlolweni kokujikeleza kokushisa okuphezulu nokuphansi kusukela ku--40 ℃ kuya ku-120 ℃, ukuguqulwa kwe-warpage kwemikhiqizo yefayibha yengilazi ende cishe ingxenye eyodwa kwezintathu kuphela yefayibha ezimfushane. Lokhu kwenza izinto ze-LGF zifaneleke kakhulu izingxenye ezinokuguquguquka okukhulu kokushisa kwangaphandle.

3. Ubunye bamandla aphezulu kanye nokukhanya okulula

Ubuningi buyi-1/2-1/3 kuphela ye-aluminium alloy (i-LGF-PP icishe ibe yi-1.0-1.2 g/cm³, i-LGF-PA66 icishe ibe yi-1.3-1.5 g/cm³), kodwa amandla athile (amandla/ubuningi) asondele noma adlula ngisho nalawo amanye ama-aluminium alloy, okwenza kube ukukhetha okuhle kokufeza "ukufaka esikhundleni sensimbi ngepulasitiki". Isibonelo, amandla okuthamba e-LGF-PP40 angafinyelela ku-120-150 MPa, kanti i-modulus yokugoba ingafinyelela ku-10-12 GPa, okwanele ukufaka esikhundleni sezinsimbi zezingxenye eziningi ezakhiwe kancane.

二,Izindawo ezijwayelekile zokusetshenziswa kanye nezidingo ezithile zezinto ezisetshenziswayo ensimini ngayinye

Izibonelo zezingxenye zemboni, izidingo ezibalulekile, izinto ezinconywayo

三Idatha Yethrendi Yemakethe

Ngokwezibalo zezinkampani zangaphandle, usayizi wemakethe yomhlaba wonke wezinto ezihlanganisiwe ze-thermoplastic eziqiniswe ngefayibha ende yengilazi kulindeleke ukuthi ufinyelele cishe amaRandi ayizigidi eziyizinkulungwane ezingu-2.8 ngo-2023, futhi kulindeleke ukuthi ufinyelele amaRandi ayizigidi eziyizinkulungwane ezingu-4.5 ngo-2030, ngesilinganiso sokukhula kwenhlanganisela yonyaka esingu-7.2%. Umthombo wedatha: Imibiko yezimboni efana neMarketsandMarkets. Phakathi kwazo, isifunda sase-Asia Pacific sinesilinganiso sokukhula esisheshayo, kanti iShayina, njengomkhiqizi omkhulu nomthengisi wepulasitiki oguquliwe, kancane kancane ithatha indawo yezinto zokusetshenziswa ezibizayo zaseYurophu naseMelika. Amandla ayinhloko okushayela inzuzo yezindleko (20% -30% ephansi kunemikhiqizo yaseYurophu naseMelika) kanye nemijikelezo yokulethwa emifushane.

四、 Indawo yethu

Inkampani yethu ibilokhu igxile ocwaningweni nasekukhiqizweni kwe-LGF-PP kanye ne-LGF-PA66 iminyaka engaphezu kwengu-20, futhi inesistimu yenqubo ezimele yobuchwepheshe obuqhubekayo bokufaka i-fiber yengilazi ende. Umkhiqizo uthunyelwe ngobuningi eYurophu, eRussia, eNingizimu-mpumalanga ye-Asia, eMpumalanga Ephakathi, eNingizimu Melika nakwezinye izifunda.

Asizisho ukuthi siwukuphela noma singcono kakhulu, kodwa kunalokho sinikeza ezinye izindlela eziqinisekisiwe. Uma kuqhathaniswa nemikhiqizo evamile yaseYurophu naseMelika efana ne-SABIC, i-Celanese, ne-DSM, inzuzo yethu ejwayelekile yezindleko ingu-20% -25%, kuyilapho sigcina ukusebenza kwayo okungu-85% -95%, okuqinisekiswe ngokuhlolwa kweqembu ngamakhasimende amaningi.

Asigcini nje ngokuhlinzeka ngamamaki ajwayelekile, kodwa futhi senza ngokwezifiso amafomula ngokuya ngezimo zokusetshenziswa kwamakhasimende (amazinga okushisa aphezulu naphansi, umswakama, amabala kawoyela, ukuvezwa ngaphandle), sisiza amakhasimende ukunciphisa kakhulu izindleko zezinto ngenkathi eqinisekisa ukusebenza kahle.Okuhlangenwe nakho okusebenzayo: Amafomula enziwe ngokwezifiso ngokuvamile adinga amasonto angu-4-6 okulungiswa kwefomula kanye nokuqinisekiswa kwesampula ngaphambi kokungena ekukhiqizweni okukhulu.
