Q Kodi mungadulire bwanji mapepala apulasitiki a ABS?

A

Kudula mapepala apulasitiki a ABS n'kosavuta ndi zida ndi njira zoyenera, kutengera makulidwe ndi kulondola komwe kumafunika. Umu ndi momwe mungachitire:

Kwa mapepala opyapyala (mpaka 1-2 mm):

Mpeni kapena chida chogoletsa: Goletsani pepalalo motsatira rula ndi ma stripes olimba, mobwerezabwereza mpaka mutadula pakati. Kenako pindani mzere wogoletsa kuti mudule bwino. Sefani m'mbali ndi sandpaper ngati pakufunika kutero.

Lumo kapena zitini: Pa mapepala opyapyala kwambiri kapena odulidwa mopingasa, lumo lolemera kapena zitini zimagwira ntchito bwino, ngakhale kuti m'mbali mungafunike kumalizidwa.

Kwa mapepala apakati (2-6mm):

Jigsaw: Gwiritsani ntchito tsamba lokhala ndi mano ochepa (10-12 TPI) lopangidwira pulasitiki. Mangani pepalalo pamalo okhazikika, lembani mzere wanu ndikudula pa liwiro loyenera kuti musamasungunuke ABS chifukwa cha kukangana. Ziziritsani tsambalo ndi madzi kapena mpweya ngati latentha kwambiri.

Sowo lozungulira: Gwiritsani ntchito tsamba lokhala ndi nsonga ya kabide (mano ambiri, 60-80 TPI). Mangani pepalalo, dulani pang'onopang'ono ndipo lithandizireni kuti lisagwedezeke kapena kusweka.

Pa mapanelo okhuthala (6mm+):

Kudula Patebulo: Monga momwe zimakhalira ndi kudula kozungulira, gwiritsani ntchito tsamba lokhala ndi mano ochepa ndikukankhira bolodilo molunjika. Gwiritsani ntchito choyikapo chopanda kuchotsera kuti muchepetse kusweka.

-Band saw: Yabwino kwambiri podula ma curve kapena makulidwe okhuthala; gwiritsani ntchito tsamba lopapatiza, lokhala ndi mano ochepa ndipo yendani pang'onopang'ono kuti muzitha kulamulira.

Malangizo ambiri:

Kulemba: Gwiritsani ntchito pensulo kapena chizindikiro chokhala ndi rula kapena chitsanzo.

Chitetezo: Valani magalasi oteteza ndi chophimba nkhope - Fumbi la ABS likhoza kukwiyitsa. Gwirani ntchito pamalo opumira mpweya.

Liwiro lolamulira: Kuthamanga kwambiri kumatha kusungunula pulasitiki; pang'onopang'ono kwambiri kumatha kuyambitsa m'mbali zokwawa. Yesani kaye pa zidutswa.

Kumaliza: Konzani m'mbali ndi sandpaper ya grit ya 120-220 kapena gwiritsani ntchito chida chochotsera ming'alu.

Q Ndi pepala liti la pulasitiki lomwe lili bwino, PVC kapena ABS?

A

Kaya PVC kapena ABS ndi 'zabwino' zimadalira zosowa zanu - chinthu chilichonse chili ndi ubwino wosiyana.

PVC ndi yolimba, yotsika mtengo, komanso yolimba kwambiri ku mankhwala, chinyezi, ndi nyengo, zomwe zimapangitsa kuti ikhale yabwino kwambiri kugwiritsidwa ntchito panja (monga mapaipi, zipilala, zizindikiro). Ndi yoletsa moto ndipo siiwonongeka ndi kuwala kwa UV mwachangu monga momwe ABS yosachiritsidwira. Komabe, siigwira ntchito kwambiri, imatha kusweka mukamazizira, ndipo siimakhala yolimba kwambiri.

Mosiyana ndi zimenezi, ABS ndi yolimba komanso yolimba, ngakhale kutentha kochepa, yokhala ndi mawonekedwe owala omwe amawonjezera kukongola (monga zida zamagalimoto, zamagetsi, zitsanzo). N'zosavuta kuumba, makina, ndi guluu; komabe, siilimbana ndi kuwala kwa UV (yomwe imafuna zokhazikika kuti zigwiritsidwe ntchito panja) ndipo imalekerera kutentha pang'ono (imasungunuka pafupifupi 105°C poyerekeza ndi PVC ya 80-100°C, kutengera mtundu wake).

Q Kodi pepala la ABS Plastiki ndi chiyani?

Pepala la ABS (Acrylonitrile Butadiene Styrene) ndi thermoplastic yogwira ntchito kwambiri yomwe imadziwika chifukwa cha kulimba kwake, kuuma kwake, komanso kukana kutentha. Thermoplastic iyi imapezeka m'magawo osiyanasiyana, imapereka zinthu zosiyanasiyana komanso ntchito zosiyanasiyana. Pepala la pulasitiki la ABS likhoza kukonzedwa pogwiritsa ntchito njira zonse zodziwika bwino zokonzera thermoplastic ndipo ndi losavuta kugwiritsa ntchito. Pepala ili limagwiritsidwa ntchito nthawi zambiri pazida zamagetsi, mkati mwa magalimoto, mkati mwa ndege, m'matumba, m'mathireyi, ndi zina zambiri. Mapepala awa amapezeka m'makulidwe osiyanasiyana, mitundu, ndi zomaliza pamwamba, akutsatira miyezo yapadziko lonse lapansi.

Q Kodi ubwino wa filimu ya polycarbonate ndi wotani?

A

♦ Wamphamvu, wolimba komanso wolimba mtima kwambiri

♦ Kukana kugunda kwambiri

♦ Kuwala bwino kwa kuwala

♦ Kukana kutentha kwambiri

♦ Kuteteza magetsi bwino

♦ Kusweka kwa nthaka, nyengo, ndi kukana mankhwala

Q Kodi filimu ya polycarbonate imagwiritsidwa ntchito pa chiyani?

Filimu ya polycarbonate imagwiritsidwa ntchito

mabatire amagetsi: gawo la batri/selo/PAKITI, batri yosungira mphamvu, ndi zina zotero.

Q Kodi filimu ya polycarbonate ndi chiyani?

Filimu ya Polycarbonate ndi chinthu cha thermoplastic chogwira ntchito bwino kwambiri chochokera ku pulasitiki ya polycarbonate. Imadziwika ndi kumveka bwino kwa kuwala, kukana kukhudza kwambiri, komanso kukhazikika kwa kutentha kwambiri. Kuphatikiza apo, ili ndi mphamvu zabwino kwambiri zamakanika, kutchinjiriza magetsi bwino, kukhazikika kwa mawonekedwe apamwamba, komanso kukana kugwedezeka kwambiri. Mafilimu a Polycarbonate amagwiritsidwa ntchito m'mafakitale osiyanasiyana monga mabatire amphamvu, zinthu zamagetsi, zida zamagalimoto, zida zapakhomo, zowonetsera zolumikizirana, zida zoteteza, ndi zina zotero.

Q Kodi ubwino wa pepala la rPET ndi wotani?

A

Si poizoni komanso yotetezeka

Kulimba kwambiri, kuuma ndi mphamvu

Kukhazikika kwakukulu

Zosavuta kupanga thermoform

Chotchinga chabwino ku mpweya ndi nthunzi ya madzi

Kapangidwe kabwino ka makina

Q Kodi pepala la rPET lingathe kubwezeretsedwanso 100%?

Inde , pepala la rPET ndi zinthu za rPET zimatha kubwezeretsedwanso 100%.

Q Kodi kusiyana pakati pa rPET ndi PET ndi kotani?

Pepala la rPET ndi pepala la polyethylene terephthalate lobwezerezedwanso, zomwe zikutanthauza kuti limachokera ku zinyalala za PET zomwe mabizinesi ndi ogula amabwezeretsanso. Mapepala a PET amapangidwa kuchokera ku tchipisi tatsopano ta PET, chinthu chochokera ku mafuta.

Q Kodi pepala la rPET ndi chiyani?

Pepala la rPET ndi pulasitiki yokhazikika yopangidwa kuchokera ku polyethylene terephthalate (rPET) yobwezeretsedwanso. Mapepala awa ali ndi zinthu zabwino za PET yoyambirira, monga mphamvu, kuwonekera bwino, komanso kukhazikika kwa kutentha. Ndi chinthu chomwe opanga amagwiritsa ntchito kwambiri kuti akwaniritse zolinga zawo zokhazikika.

Q Kodi mathireyi a cpet ndi chiyani?

Mathireyi a CPET, kapena mathireyi a Crystalline Polyethylene Terephthalate, ndi mtundu wa maphukusi a chakudya opangidwa kuchokera ku mtundu winawake wa zinthu zopangidwa ndi thermoplastic. CPET imadziwika kuti imapirira kutentha kwambiri komanso kotsika, zomwe zimapangitsa kuti ikhale chisankho chodziwika bwino pamitundu yosiyanasiyana ya maphukusi a chakudya.

Q Kodi thireyi ya pulasitiki ya CPET imatha kuphikidwa mu uvuni?

Inde , mathireyi apulasitiki a CPET amatha kuphikidwa mu uvuni. Amatha kupirira kutentha kuyambira -40°C mpaka 220°C (-40°F mpaka 428°F), zomwe zimathandiza kuti azigwiritsidwa ntchito mu ma uvuni a microwave, ma uvuni wamba, komanso malo osungiramo zinthu ozizira.

Q Kodi kusiyana kwa thireyi ya CPET ndi thireyi ya PP ndi kotani?

Kusiyana kwakukulu pakati pa mathireyi a CPET ndi mathireyi a PP (Polypropylene) ndi kukana kutentha ndi zinthu zomwe zili mkati mwake. Mathireyi a CPET ndi otetezedwa kutentha kwambiri ndipo angagwiritsidwe ntchito mu uvuni wa microwave ndi wamba, pomwe mathireyi a PP nthawi zambiri amagwiritsidwa ntchito poika ma microwave kapena kusungiramo zinthu zozizira. CPET imapereka kulimba bwino komanso kukana kusweka, pomwe mathireyi a PP ndi osinthika kwambiri ndipo nthawi zina amakhala otsika mtengo.

Q Kodi mathireyi a CPET amagwiritsidwa ntchito popanga chakudya chotani?

Mathireyi a CPET amagwiritsidwa ntchito popangira zakudya zosiyanasiyana, kuphatikizapo chakudya chokonzeka, zinthu zophika buledi, zakudya zozizira, ndi zinthu zina zomwe zimawonongeka zomwe zimafunika kutenthedwanso kapena kuphikidwa mu uvuni kapena mu microwave.

Q CPET vs PET

CPET ndi PET zonse ndi mitundu ya ma polyester, koma ali ndi makhalidwe osiyanasiyana chifukwa cha kapangidwe ka mamolekyu awo. CPET ndi mtundu wa PET wopangidwa ndi kristalo, womwe umapangitsa kuti ikhale yolimba komanso yolimba kwambiri kutentha kwambiri komanso kotsika. PET nthawi zambiri imagwiritsidwa ntchito pamabotolo a zakumwa, ziwiya za chakudya, ndi zina zomwe zimayikidwa m'mabokosi zomwe sizifuna kutentha kofanana. PET ndi yowonekera bwino, pomwe CPET nthawi zambiri imakhala yosawonekera bwino kapena yowonekera pang'ono.
