Nkhani - ndi payipi iti ya ptfe yosinthasintha kapena payipi ya polyurethane

Ndi ntchito iti yabwino kwambiri

Chubu cha PTFE ndi chubu cha PU zonse zimagwiritsidwa ntchito kwambiri m'mafakitale osiyanasiyana, koma malo ogwiritsira ntchito awiriwa si ofanana. Chubu cha PTFE chimagwiritsidwa ntchito m'malo ogwirira ntchito ovuta kwambiri, ndipo kukula kwake ndi kokwanira, mafakitale oyenerera ndi okulirapo kuposa chubu cha PU. Chitoliro cha PU ndi choyenera kugwira ntchito pansi pa kupanikizika ndi kutentha kwabwinobwino. Chifukwa chakuti zinthu zake ndi zofewa komanso zotanuka, zimatha kupindika momwe mukufunira. Ndi yoyenera kwambiri m'malo opapatiza kapena m'malo okhala ndi radius yopindika kwambiri.

Apa ndi momwe mungafotokozere mwatsatanetsatane mitundu iwiri ya machubu:

Chubu cha PTFE:

Chitoliro cha Ptfe ndi chitoliro chapadera chopangidwa ndi zinthu za PTFE pambuyo potulutsa ndi kusungunula, kuumitsa, kusungunula kutentha kwambiri, ndi kupanga mawonekedwe. Polytetrafluoroethylene (PTFE) ili ndi kukhazikika kwabwino kwa mankhwala, monga:

1. Yolimba ku kutentha kwakukulu ndi kuthamanga kwambiri. Itha kugwiritsidwa ntchito kwa nthawi yayitali pa -65℃ ~ 250℃ pansi pa kuthamanga kwabwinobwino. Pambuyo pa maola 1000 a kutentha kwakukulu pa 250℃, mawonekedwe ake amakina sasintha kwenikweni.

2. Yoletsa dzimbiri komanso yoletsa ukalamba, imatha kupirira ma asidi onse amphamvu, ma alkali amphamvu, ma oxidant amphamvu, ndipo sigwirizana ndi zinthu zosiyanasiyana zachilengedwe.

3. Chotetezera kutentha. Popeza PTFE ilibe polarity, kukana kutentha komanso kusayamwa madzi, ndi chinthu chabwino kwambiri chotetezera kutentha chamagetsi.

4. Kuchuluka kwa kupsinjika kochepa. PTFE ili ndi kuchuluka kwa kupsinjika kochepa kwambiri. Ndi chinthu chabwino choletsa kupsinjika komanso chodzipaka chokha. Kuchuluka kwake kwa kupsinjika kosasinthasintha ndi kochepa kuposa kuchuluka kwa kupsinjika kwamphamvu. Chifukwa chake, ili ndi ubwino wochepa kuyambira komanso kuyenda bwino ikagwiritsidwa ntchito popanga ma bearing.

5. Chosayaka moto, chopanda poizoni, chopepuka, chosinthasintha bwino komanso mawonekedwe ena, chogwiritsidwa ntchito mosiyanasiyana, chosavuta kuwononga, chokhala ndi moyo wautali, chosafunikira kusinthidwa pafupipafupi ndiye chinthu chofunikira kwambiri

Cholinga cha chitoliro cha PU:

Amagwiritsidwa ntchito kwambiri m'magalimoto, ndege, ma hydraulic, ma pneumatics, njanji, kukonza chakudya, zida zoyendera madzi, mayendedwe a mankhwala, kupanga ndi petrochemical, zotchingira zamagetsi, ndi zina zotero.

Paipi ya polyurethane:

Chubu cha polyurethane ndi chubu cha PU, chogawidwa m'machubu olimba ndi payipi, chubu chowonekera, ndi zina zotero. Chinthu chachikulu ndichakuti chubucho ndi chofewa ndipo chimatha kupindika pang'ono kwambiri. Chifukwa cha kupepuka kwake ndi kufewa, ndi chosavuta kugwiritsa ntchito. Mapayipi a PU amagwiritsidwa ntchito kwambiri pamapayipi a mpweya, mapaipi amadzi ndi mapaipi onyamula zinthu okhala ndi kuthamanga kwabwinobwino komanso kutentha. Koma poyerekeza ndi mapaipi a PTFE, mapaipi a PU amatha kukalamba komanso hydrolysis ndipo amakhala ndi moyo waufupi wautumiki. Kukhazikika kwa mankhwala ndi kochepa, monga:

1. Kutentha kwa ntchito kuli pakati pa -20° ndi +60°;

2. Kukana dzimbiri ndi kofooka, sikungathe kupirira ma asidi amphamvu ndi ma alkali, ndipo kumakumana mosavuta ndi mankhwala awa.

3. Kupanikizika kwa ntchito kuli mkati mwa 10kg yokha, komwe sikungagwiritsidwe ntchito pamalo ogwirira ntchito omwe ali ndi kuthamanga kwambiri.

4. Kukana kuvala mwamphamvu, kuli ndi ntchito zosiyanasiyana poyendetsa zinthu.

5. Chitoliro chopindika ndi chaching'ono. Chifukwa chitoliro cha PU ndi chofewa komanso cholimba bwino, ndi choyenera kumanga mapaipi.

6. Chubu cha PU chili ndi mawonekedwe owonekera bwino, ndipo momwe madzi amayendera bwino zimaonekera bwino.

Cholinga cha chitoliro cha PU:

Ndi yoyenera mafakitale, ulimi, chakudya, mankhwala, uinjiniya wa zomangamanga, usodzi, ulimi wa m'madzi, ulimi wa m'minda, mafuta osawononga ndi madera ena. Ngati ikufunika kukhala ndi moyo wautali, iyenera kukhala ndi mphamvu yogwira ntchito komanso chilengedwe. Ikagwiritsidwa ntchito kutentha. Pamene kutentha kukukwera, mphamvu yogwirira ntchito iyenera kuchepa moyenerera. Ngati malire apitirira, payipi ikhoza kuphulika. Kutentha kwa madzi kumakhala kwakukulu kwambiri kapena madziwo ali ndi ndalama zowononga mankhwala, zomwe zingayambitse payipi kuphulika, kutentha kwa malo ogwirira ntchito kumakhala kwakukulu kwambiri kapena malo ogwirira ntchito ali ndi mpweya wa mankhwala, zomwe zingayambitse payipi kusweka, kusungidwa pamalo onyowa kapena nthawi yosungira yatha. Nthawi yayitali, idzasungunuka ndi madzi kapena kukalamba payipi, zomwe zingayambitse kusweka.
