Kuchita kwakukulu

a.Mphamvu zamakina: mphamvu yayikulu, kukana kutopa, kukhazikika kwa mawonekedwe, ndi kukwapula kwakung'ono (zochepa zosintha pansi pa kutentha kwakukulu);
b.Kukana kukalamba kwa kutentha: index yowonjezereka ya kutentha kwa UL imafika 120 ~ 140 ℃ (kukalamba kwakunja kwanthawi yayitali ndikwabwino kwambiri);

c.Kukaniza zosungunulira: palibe kusweka kwa nkhawa;

d.Kukhazikika kwa madzi: zosavuta kuwola pokhudzana ndi madzi (gwiritsani ntchito mosamala pa kutentha kwakukulu ndi kutentha kwakukulu);

e.Magetsi:

1. Kuchita kwa insulation: zabwino kwambiri (zimatha kusunga magetsi okhazikika ngakhale pansi pa chinyezi ndi kutentha kwakukulu, ndizinthu zabwino zopangira zida zamagetsi ndi zamagetsi);

2. Dielectric coefficient: 3.0-3.2;

3. Arc kukana: 120s

f.Kupanga processability: jekeseni akamaumba kapena extrusion akamaumba ndi zida wamba.Chifukwa cha liwiro la kristalo komanso kuthamanga kwamadzi abwino, kutentha kwa nkhungu kumatsikanso kuposa mapulasitiki ena aumisiri.Mukakonza zigawo zokhala ndi mipanda yopyapyala, zimangotenga masekondi angapo, ndipo zimangotenga 40-60s pazigawo zazikulu.

ntchito

a.Zipangizo zamagetsi: zolumikizira, zosinthira, zida zapakhomo, zida zowonjezera, zophimba zazing'ono zamagetsi kapena (kukana kutentha, kukana lawi, kutchinjiriza kwamagetsi, kukhazikika kwamagetsi);

b.Galimoto:

1. Zigawo zakunja: makamaka zimaphatikizapo ma gridi angodya, chivundikiro cha mpweya wa injini, ndi zina zotero;

2. Zigawo zamkati: makamaka zikuphatikizapo endoscope amakhala, wiper bulaketi ndi valavu dongosolo control;

3. Magawo amagetsi agalimoto: machubu opotoka amagalimoto opotoka ndi zolumikizira zamagetsi zosiyanasiyana, etc.

c.Zipangizo zamakina: shaft yoyendetsa lamba ya chojambulira kanema, chivundikiro cha makompyuta apakompyuta, chivundikiro cha nyali ya mercury, chivundikiro chachitsulo chamagetsi, zida zamakina ophikira ndi magiya ambiri, makamera, mabatani, mawotchi apakompyuta, magawo a kamera ( ndi kukana kutentha, Zofunikira zoletsa moto)

Kugwirizana

Malinga ndi zosowa zosiyanasiyana, mutha kusankha zomatira zotsatirazi:

1. G-955: Chigawo chimodzi kutentha kutentha kuchiritsa zomata zotanuka shockproof, kugonjetsedwa ndi kutentha kwapamwamba ndi otsika, koma liwiro lomangira ndi pang'onopang'ono, guluu nthawi zambiri amatenga tsiku 1 kapena masiku angapo kuchiza.

2. KD-833 yomatira pompopompo imatha kulumikiza pulasitiki ya PS mwachangu mumasekondi pang'ono kapena masekondi makumi angapo, koma zomatira zimakhala zolimba komanso zolimba, ndipo sizilimbana ndi kumizidwa m'madzi otentha kuposa madigiri 60.

3. QN-505, guluu zigawo ziwiri, zomangira zofewa wosanjikiza, oyenera PS lalikulu dera kugwirizana kapena kuonjezera.Koma kutentha kwambiri kukana ndi koipa.

4. QN-906: Guluu wamagulu awiri, kukana kutentha kwambiri.

5. G-988: Chigawo chimodzi cha kutentha kwa chipinda vulcanizate.Ikachiritsa, ndi elastomer yokhala ndi zomatira zosalowerera madzi, zomatira zosagwedezeka, kukana kutentha kwambiri komanso kutsika.Ngati makulidwe ake ndi 1-2mm, amachiritsa pambuyo pa maola 5-6 ndipo ali ndi mphamvu zina.Zimatenga maola osachepera 24 kuti muchiritse.Chigawo chimodzi, palibe chifukwa chosakaniza, ingogwiritsani ntchito mutatha kutulutsa ndipo mulole kuyima popanda kutentha.

6. KD-5600: UV kuchiritsa zomatira, kugwirizana mandala mapepala PS ndi mbale, sangathe kukwaniritsa zotsatira, ayenera kuchiritsidwa ndi ultraviolet kuwala.Zotsatira zake zimakhala zokongola pambuyo pomamatira.Koma kutentha kwambiri kukana ndi koipa.

Kuchita kwakuthupi

Kusungunula kwamagetsi kwabwino kwambiri (makamaka kusungunula kwamphamvu kwambiri), kosawoneka bwino komanso kosawoneka bwino, kutulutsa kuwala kwachiwiri kwa plexiglass, coloration, madzi osasunthika, kukhazikika kwamankhwala, mphamvu zambiri, koma zolimba, zosavuta kuyambitsa kupsinjika, komanso kusalolera Zosungunulira za organic monga benzene. ndi petulo.Oyenera kupanga insulating mbali mandala, mbali zokongoletsera, zida mankhwala, zida kuwala ndi mbali zina.

Kupanga magwiridwe

- Zinthu za amorphous, kuyamwa kwa chinyezi chochepa, siziyenera kuuma mokwanira, ndipo sizovuta kuwonongeka, koma coefficient of thermal expansion ndi yayikulu, ndipo n'zosavuta kutulutsa kupsinjika kwamkati.Imakhala ndi madzi abwino ndipo imatha kupangidwa ndi makina ojambulira phula kapena plunger.

⒉Ndikoyenera kugwiritsa ntchito kutentha kwakuthupi, kutentha kwa nkhungu, komanso kutsika kwa jekeseni.Kutalikitsa nthawi ya jekeseni kumapindulitsa kuchepetsa kupsinjika kwa mkati ndikuletsa kuchepa ndi kusinthika.

⒊ Mitundu yosiyanasiyana ya zipata ingagwiritsidwe ntchito, ndipo zipata zimagwirizanitsidwa ndi zigawo za pulasitiki kuti zipewe kuwonongeka kwa zigawo za pulasitiki pamene chipata chikuchotsedwa.Mbali yoyimitsa ndi yayikulu ndipo ejection ndi yofanana.Makulidwe a khoma la zigawo za pulasitiki ndi yunifolomu, makamaka popanda zoikamo, monga Zina zoyika ziyenera kutenthedwa.

ntchito

PS imagwiritsidwa ntchito kwambiri pamakampani opanga kuwala chifukwa chamayendedwe ake abwino.Ikhoza kugwiritsidwa ntchito popanga magalasi opangira magalasi ndi zida zowoneka bwino, komanso mitundu yowonekera kapena yowala, monga nyali, zida zowunikira, ndi zina zotero. PS imatha kupanganso zida zambiri zamagetsi ndi zida zomwe zimagwira ntchito pamalo okwera kwambiri.Popeza pulasitiki ya PS ndi chinthu chovuta kuyika pamwamba, ndikofunikira kugwiritsa ntchito guluu waukadaulo wa PS kuti mugwirizane ndimakampani.

Kugwiritsa ntchito PS kokha ngati chinthu kumakhala ndi brittleness yayikulu.Kuonjezera zinthu zina zazing'ono ku PS, monga butadiene, kungathe kuchepetsa kwambiri brittleness ndikuwongolera kulimba kwake.Pulasitiki iyi imatchedwa PS yosagwira ntchito, ndipo makina ake amapangidwa bwino kwambiri.Zida zambiri zamakina ndi zida zomwe zimagwira ntchito bwino kwambiri zimapangidwa ndi mapulasitiki.
