1. Kev ua cov khoom siv raw: hloov cov fiber ntau thiab txhim kho cov qauv
Qhov kev xaiv ntawm cov khoom siv raw rau ntim cov khoom siv hauv tsev muaj qhov cuam tshuam ncaj qha rau lawv qhov muaj zog npaum li cas. Cov kev daws teeb meem feem ntau tam sim no yog:
Tshuab rau fiber ntau compounding: Koj tuaj yeem txhim kho qhov tensile Performance index los ntawm 22% thiab qhov ntsuas tawg los ntawm 65.8% los ntawm kev sib xyaw broad -tev ntoo pulp (uas ua rau nws yooj yim dua) nrog bagasse pulp (uas ua rau nws muaj zog thaum compressed) hauv 1: 1 piv. Piv txwv li, ib lub chaw tsim tshuaj paus tau ua ib lub tais rau lub tshuab cua txias uas tuaj yeem tuav 20% ntau qhov hnyav los ntawm kev ntxiv 20% ntxhia fibers.
Ntxiv cov tshuaj ntxiv: Ntxiv aluminium sulfate (cov khoom siv tsis muaj dej tsis muaj dej) thiab nano silica (pob hydrophobic) rau cov txheej txheem kev npaj slurry tuaj yeem txiav tus nqi uas cov dej nqus tau los ntawm 15% mus rau tsawg dua 3%. Los ntawm nano txheej thev naus laus zis, qee hom ntim cov tub yees khaws cia 85% ntawm nws lub zog qub hauv chav nrog 90% av noo.
Txhim kho qhov zoo rau ib puag ncig: Cationic starch ua fibers lo ua ke zoo dua los ntawm kev tsim hydrogen bonds. Ntxiv 1% tuaj yeem ua rau lub zog tensile nce mus txog 30%. Epoxy-coated sodium bicarbonate microcapsules tsim cov qauv microporous los ntawm kev tso roj, uas ua rau lawv sib zog thiab zoo dua ntawm compressing.
2. Cov txheej txheem ntawm kev tsim muaj xws li lub tshuab nqus tsev nqus thiab ua kom cov qauv muaj zog.
Thaum ua ntim rau cov khoom siv hauv tsev, koj yuav tsum nrhiav qhov sib npaug ntawm qhov raug thiab ceev. Qee cov cuab yeej siv feem ntau thiab cov kev siv niaj hnub no yog:
Txoj kev ntawm lub tshuab nqus tsev suction molding:
Nruas- hom tshuab yog qhov zoo rau kev ua cov khoom loj, qauv zoo li cov tais hauv qab lub tub yees. Lawv ua kom muaj txiaj ntsig zoo dua los ntawm kev tig lawv tsis tu ncua, tab sis lawv raug nqi ntau dua los ua pwm.
Round ncig lifting khoom: ib txheej ntawm concave pwm thiab ib txheej ntawm convex pwm ua hauj lwm ua ke los nqa khoom. Qhov no tsis xav tau CNC chaw ua haujlwm. Nws yog qhov zoo rau ntim cov khoom me me ntawm cov khoom siv hauv tsev uas tsis yog tus qauv (xws li lub tshuab ntxhua khaub ncaws). Lub voj voog ntau lawm yog txwv rau 10 hnub.
Moulding nrog kev pab los ntawm huab cua compressed: Los ntawm kev ua kom cov deposition ntawm fibers siv lub siab zoo, lub sij hawm molding yog txiav los ntawm 30% thiab qhov ntom ntawm cov khoom yog ntau dua.
Tsim kom muaj kev txhawb nqa kev tsim kho:
Honeycomb qauv: Cov qauv tsim no zoo li lub koom haum hexagonal ntawm lub honeycomb. Hauv kev ntsuas 1-meter poob, nws txiav lub ncov acceleration ntawm lub tshuab ntxhua khaub ncaws los ntawm 27%.
Gradient density structure: By adjusting the density of the fiber deposition, the packing surface density is high to withstand impact, while the inside density is low to absorb energy. Nrog rau cov txheej txheem no, Apple tau ua lub xov tooj ntim 20% thinner thaum khaws tib qib kev tiv thaiv.
Ua ribs thiab kab noj hniav kom muaj zog: Siv siab - kub thiab siab - siab sib xyaw los ua ntau- txheej txheej txheej hauv TV ntim uas muaj 30% mus rau 50% muaj zog tiv thaiv compression.
3. Qhuav thiab shaping: kub nias thiab tswj cov tsis
Cov txheej txheem ziab muaj qhov cuam tshuam ncaj qha rau ntawm lub ntim cov khoom siv zoo thiab qhov ruaj khov:
Kev ziab nrog pwm: Cov khoom yog qhuav hauv pwm nrog qhov tseeb qhov tseeb ntawm ± 0.1mm. Qhov no yog qhov zoo rau siab -kawg cov khoom siv hauv tsev, suav nrog liner rau cov cua txias. Ib lub tuam txhab ntiav cov roj cua sov kom sov nws cov tsev thiab kho qhov kub ntawm lub tshuab taub hau, tus Tsov tus tw, thiab qhov chaw cua sov kom ua kom cov txheej txheem ziab kom qhuav 40% ntau dua.
Demolding thiab ziab: Thaum cov khoom raug tshem tawm ntawm pwm, nws qhuav ntawm tus nqi txo tab sis nrog tus nqi qis dua. Ntxiv 0.5% tus neeg sawv cev ntub dej tuaj yeem txiav qhov shrinkage ntawm 5% mus rau 1.5%.
Peb feem ntawm kub nias thiab shaping:
Siab: Kom paub tseeb tias cov fibers lo ua ke zoo, chav tsev siab ntawm qhov projected cheeb tsam yuav tsum khaws cia ntawm 0.4 thiab 0.6 MPa.
Qhov kub nyob rau hauv pwm kab noj hniav yuav tsum yog 180-200℃kom soften lub hemicellulose thiab ua hydrogen bonds.
Sijhawm: Hloov lub sijhawm raws li qhov tuab ntawm cov khoom. Nws yuav siv sij hawm 30 mus rau 50 vib nas this los tsim nws. Los ntawm kev ncua lub sijhawm kub kub mus rau 60 vib nas this, qee yam ntawm lub thawv ntim khoom txias ua rau lub kaum sab xis compressive zog 15% muaj zog dua.
4. Tshaj tawm - ua tiav: ua kom muaj txiaj ntsig thiab zoo dua
Kev kho ntawm qhov chaw
Waterproof txheej: Lub thawv yog txau nrog dej -raws li polyurethane los yog acrylic lotion, uas ua rau nws IPX4 waterproof.
Anti- kev kho zoo li qub: Cov graphene conductive txheej ua kom lub ntsej muag tiv thaiv ntawm 10 ⁶ thiab 10 ⁹ Ω / sq, uas tiv thaiv cov khoom hluav taws xob los ntawm kev puas tsuaj.
Etching thiab nyem thev naus laus zis: Ntxiv tus nqi rau ntim los ntawm kev ua cov qauv xuab zeb zoo lossis hom logo nyem rau saum npoo ntawm cov pwm kab noj hniav. Peb- thev naus laus zis thev naus laus zis tau ua rau qhov kev paub tsis muaj kev tshaj tawm 30% zoo dua rau siab - kawg TVs.
Txiav thiab folding ntug:
Ntiv nplhaib txiav txheej txheem: Txiav 2 mus rau 4 yam khoom ib zaug, siv ib qho - ib sab qhov nrug ntawm 10 mus rau 15 mm kom burrs kom tsawg.
V-groove folding: Thaum koj siv V-groove fixtures los ua cov grooves nrog "V" zoo li tus ntoo khaub lig-section, ob sab ntawm folded zawj haum ua ke ruaj ntseg, ua rau cov qauv ruaj khov.
Xyuas qhov zoo:
Siv lub tshuab kuaj cov khoom siv thoob ntiaj teb los muab 500 kg ntawm lub zog ntawm lub ntim thiab saib seb nws puas deforms tsawg dua 3 hli.
Kev sim poob: Tshawb xyuas kev ua haujlwm puas tsuaj rau cov khoom los ntawm kev xa nws los ntawm qhov siab ntawm 1 meter.
Dhau EU EN13432 biodegradable tus qauv thiab FSC (Forest Stewardship Council) ntawv pov thawj kom ua tau raws li cov qauv xa tawm.
