Chubu cha PTFE chosinthika chosinthika China imapanga

Zinthu Zogulitsa:

Mbali yaikulu yaMachubu Ozungulira a PTFENdikuti imakhala ndi kusinthasintha kwakukulu komanso kupindika, ndipo utali wake wocheperako umawonjezeka ndi kukula kwa m'mimba mwake wa chubu. Chubu chopindikachi chili ndi mawonekedwe a PTFE, komanso chimakhala ndi kusinthasintha kwakukulu komanso kusinthasintha. Malinga ndi mawonekedwe ake opindika, pali mitundu itatu: Mtundu wa V, Mtundu wa U ndi Mtundu wa Ω. Monga cholumikizira cha payipi yolimbana ndi dzimbiri, chimagwira ntchito yoyamwa kusintha kwa kutalika kwa payipi komwe kumachitika chifukwa cha kufalikira ndi kupindika kwa kutentha, ndipo chili ndi gawo lolumikizana mozungulira kwa payipi yolimba komanso yofooka.

Pofuna kukonza magwiridwe antchito, chubu chopindika chimathanso kulimbitsa ndi mphete zachitsulo, manja achitsulo, rabala, ndi zina zotero. Chubu chopindika chamkati chimapangidwa ndi utomoni wa PTFE 100%, womwe umazunguliridwa kukhala chubu chopindika chozungulira, chomwe chimagwiritsidwa ntchito ngati chubu choteteza waya ndikunyamula zinthu zowononga.

Pakadali pano, machubu ambiri ozungulira omwe ali pamsika amapangidwa ndi zinthu za PE kapena PVC, zomwe sizimalimbana ndi kutentha ndi dzimbiri kuposa PTFE. Kuphatikiza apo, machubu ozungulira a PTFE alinso ndi kukana dzimbiri bwino, kusinthasintha kwakukulu komanso kusinthasintha, mphamvu zabwino kwambiri za dielectric, komanso kukana kukalamba komanso kukhala ndi moyo wautali.

Kapangidwe ka mankhwala:

1. Ndi kutentha kwakukulu komanso kukana kutentha kochepa kwa kutentha kwakukulu, kutentha kwake kwakukulu kumafika 250℃, ndipo kutentha kotsika kwambiri kumatha kuchepetsedwa kufika -65℃.

2. Ndi makhalidwe a kukana dzimbiri, imatha kupirira mphamvu zonse za asidi amphamvu (kuphatikizapo madzi achifumu), ma oxidant amphamvu, zochepetsera zinthu ndi zinthu zosiyanasiyana zachilengedwe kupatula chitsulo chosungunuka cha alkali, fluorinated medium ndi sodium hydroxide pamwamba pa 300℃. Itha kugwiritsidwa ntchito m'mapaipi amphamvu a asidi ndi alkaline.

3. Imakhala ndi mphamvu yolimbana ndi ukalamba, kukana ukalamba mumlengalenga, kukana kuwala kwa dzuwa komanso kulola kuti mpweya ulowerere pang'ono. Kuwonekera kwa nthawi yayitali mumlengalenga, pamwamba ndi magwiridwe antchito ake zimakhalabe chimodzimodzi, nthawi yogwirira ntchito.

4. Si poizoni komanso yotetezeka, ndipo ingagwiritsidwe ntchito popereka zakumwa zosiyanasiyana.

5. Kapangidwe kake kosayaka: chizindikiro choletsa mpweya chili pansi pa 90.

6. Kupotoka kwakukulu komanso kusinthasintha.

7. Machubu a PTFE okhala ndi corrugated angagwiritsidwenso ntchito pa mphete zachitsulo, zophimba zitsulo, rabara ndi zina zowonjezera mphamvu.

8. Ingagwiritsidwe ntchito kulumikiza zolumikizira zosayenera za mapaipi akuluakulu olimba komanso ofooka.

kagwiritsidwe ntchito:

1. Itha kugwiritsidwa ntchito ngati choyatsira ndi chosinthira machubu nthawi zapadera;

2. Itha kugwiritsidwa ntchito ngati chitoliro chodyetsera ndi kutulutsa mafuta cha galimoto ya thanki, thanki yosungiramo zinthu, chidebe ndi ketulo yochitira zinthu;

3. Itha kugwiritsidwa ntchito m'malo mwa graphite, ceramic, galasi ndi mapaipi ena okhala ndi mphamvu zochepa zamakanika;

4. Itha kugwiritsidwa ntchito polumikiza chubu molakwika kapena kugwiritsidwa ntchito polinganiza kusamuka kwa chubu ndi kusintha kwa miyeso komwe kumachitika chifukwa cha nyengo kapena zifukwa zina kapena kuthetsa kugwedezeka kwa makina kwamphamvu.

Machubu onse amalandira zopangidwa mwamakonda zomwe zitha kuperekedwa zodulidwa kutalika kwake, pamodzi ndi malekezero owongoka, opindika kapena opindika kuti zigwirizane mosavuta. Ngati mukufuna kuyesa machubu athu kuti agwiritse ntchito, titha kukupatsirani zitsanzo zaulere.
