Umthelela Wezakhiwo Zezinto Ezibonakalayo Ekusebenzeni Kwepayipi Lenjoloba Yezimboni

I-PASIONHOSE-

Ipayipi lerabha lezimboni liyingxenye eguquguqukayo kakhulu futhi ebaluleke kakhulu yezicelo eziningi ezimbonini ezahlukahlukene. Liyipayipi eliguquguqukayo elenzelwe ukuthutha uketshezi, njengamanzi, umoya, namakhemikhali, ukusuka endaweni eyodwa kuya kwenye. Amandla amapayipi erabha okumelana nokucindezela okuphezulu, izinga lokushisa, ukuhuzuka, namakhemikhali kunqunywa yizakhiwo zezinto zamakhemikhali erabha asetshenziswayo. Kulesi sihloko, sizohlola umthelela wezakhiwo zezinto ekusebenzeni kwamapayipi erabha ezimboni.

Izakhiwo Zezinto Ezihlanganisiwe Zenjoloba

Izakhiwo zamakhemikhali enjoloba asetshenziswa ekukhiqizeni amapayipi enjoloba ezimbonini zinquma izici zawo zokusebenza. Izakhiwo ezimbili eziyinhloko zamakhemikhali enjoloba ubulukhuni kanye nokunwebeka, okulinganiswa ogwini lolwandle isikali sobulukhuni A kanye nobude esikalini sokuphuka, ngokulandelana. Ezinye izakhiwo ezibalulekile zifaka phakathi amandla okudonswa, ukumelana nokudabuka, isethi yokucindezela, kanye nokumelana nokuhuzuka.

Ukuqina kwerabha kungenye yezimpawu ezibaluleke kakhulu ezithinta ukusebenza kwayo. Uma irabha ilukhuni, imelana kakhulu nokuklwebheka kanye namandla okucheba. Kodwa-ke, futhi kuyenza ingaguquguquki futhi ithambekele ekuqhekekeni emazingeni okushisa aphezulu. Ukuqina kwerabha kunquma ikhono layo lokwelula nokubuyela esimweni sayo sokuqala ngaphandle kokuguquka noma ukuphuka.

Amandla okudonseka angenye into ebalulekile ethinta ukusebenza kwepayipi lerabha. Kuyindlela yokulinganisa ikhono lerabha lokumelana nokuguquguquka lapho libhekene namandla angaphandle. Ama-compound erabha anamandla okudonseka aphezulu ahlala isikhathi eside futhi angamelana nokucindezeleka okukhulu ngaphandle kokuqhekeka.

Umthelela Wezakhiwo Zezinto Ezibonakalayo Ekusebenzeni Kwepayipi Lerabha

Izakhiwo zezinto ezibonakalayo zamakhemikhali enjoloba asetshenziswa ekukhiqizeni amapayipi ezimboni zinomthelela oqondile ekusebenzeni kwawo. Ngezansi kunezindlela ezinhlanu izakhiwo zezinto ezibonakalayo ezithinta ngazo ukusebenza kwamapayipi enjoloba.

1. Ukumelana Nokuguguleka

Amapayipi enjoloba angase aguguleke uma esetshenziswa ezimbonini ezifana nezezimayini, uwoyela, kanye negesi, lapho ehlangana khona nezindawo ezimagebhugebhu kanye nemiphetho ebukhali. Ukumelana nokuguguleka kwamakhemikhali enjoloba asetshenziswa ekukhiqizeni amapayipi kubalulekile ekunqumeni isikhathi sokuphila nokusebenza kahle kwepayipi. Amakhemikhali enjoloba asebenza kahle kakhulu anokumelana nokuguguleka okuhle kakhulu, njenge-chloroprene kanye ne-neoprene, angamelana nezimo ezinzima futhi ahlale isikhathi eside.

2. Ukumelana namakhemikhali

Ukumelana namakhemikhali kungenye imfanelo ebalulekile yamakhemikhali enjoloba athinta ukusebenza kwepayipi. Kuye ngokusetshenziswa, amapayipi angadinga ukuthutha amakhemikhali, njenge-asidi kanye nezinyibilikisi, angabangela ukuwohloka kwerabha. Ukumelana namakhemikhali kwamakhemikhali enjoloba kuyahlukahluka, futhi ukukhetha inhlanganisela efanele yokusetshenziswa okuthile kubalulekile ukuze ipayipi lihlale isikhathi eside.

3. Ukumelana Nokushisa

Amapayipi erabha avame ukuchayeka emazingeni okushisa aphezulu, kokubili ashisayo nabandayo, ezisetshenziswa ezimbonini. Ukumelana nokushisa kwamakhemikhali erabha kuthinta ikhono lepayipi lokugcina izakhiwo zalo zomzimba, njengokunwebeka nokuqina, ngaphansi kwezimo zokushisa ezihlukene. Amakhemikhali okushisa aphezulu, njenge-silicone, angamelana namazinga okushisa afinyelela ku-450°F, kuyilapho amakhemikhali okushisa aphansi, njenge-fluorocarbon, angamelana namazinga okushisa aphansi afinyelela ku--20°F.

4. Isilinganiso Sokucindezela

Isilinganiso sokucindezela kwepayipi lerabha sinqunywa ukwakheka kwalo, ukuqinisa, kanye namandla okudonsa enhlanganisela yerabha. Amakhemikhali erabha anamandla okudonsa aphezulu angamelana nokucindezela kwangaphakathi okukhulu, okuholela kumapayipi afanele ukusetshenziswa kokucindezela okuphezulu.

5. Ukuzivumelanisa nezimo

Ukuguquguquka kungenye imfanelo ebalulekile yamapayipi enjoloba ethinta ukusebenza kwawo. Amapayipi aguquguqukayo angagoba futhi aguqe ngaphandle kokulahlekelwa ukuma noma ubuqotho bawo, okwenza abe afanele ukusetshenziswa ezindaweni eziqinile. Inhlanganisela yenjoloba enokuguquguquka okuphezulu, njengenjoloba yemvelo kanye ne-EPDM, yenza amapayipi aguquguquke futhi aqine kakhudlwana.

Isiphetho

Ukusebenza kwamapayipi enjoloba ezimbonini kuncike kakhulu ezicini zezinto zokwakha zama-compound enjoloba asetshenziswa ekukhiqizweni kwawo. Ukukhetha i-compound yenjoloba efanele yokusetshenziswa okuthile kubalulekile ekunqumeni ukusebenza kwepayipi, ukuqina, kanye nokusebenza kahle. Ngokuqonda umthelela wezakhiwo zezinto ekusebenzeni kwepayipi lenjoloba, izimboni zingenza izinqumo ezinolwazi lapho zikhetha amapayipi ahlangabezana nezidingo zazo ezithile zokusetshenziswa.
