Asbhestosi: Izakhiwo kanye Izicelo

umkhakha Modern libhekene ezindaweni ezinodlame kanye okushisa aphakeme. Ngakho-ke okwadala isidingo sezindawo uphawu izinto labo abazokwazi ezisebenza ezindaweni nokhahlo. izimfuneko ezinjalo impahla ziyaphikisana futhi ngempela eziyinkimbinkimbi.

Ngakolunye uhlangothi kumelwe babe abaphile ukumelana hhayi thermally kuphela kodwa futhi amakhemikhali, kodwa ngakolunye uhlangothi - kufanele zivumelanise nezimo futhi musa chaza noma kuphela noma ophansi.

It is a jikelele impahla ukubekwa uphawu esinjalo paronit.

Asbhestosi kuyindlela eyinkimbinkimbi okuyinto e yawo yamakhemikhali Ukwakheka yakhiwa:
- kufika ku-70% we-asbestos;
- mayelana 15% zokwenziwa iraba;
- cishe 8% elapha ejenti ezifana yisibabule;
- mayelana 15% fillers ekhethekile.

Lena kuphela cishe Ukwakheka paronita. Asbhestosi elikhona inqwaba, ivumela impahla ukuze basebentise emazingeni laphakeme ukumelana ezishisayo kanye amakhemikhali. A zokwenziwa iraba ulunika Ukuzivumelanisa nezimo xaxa.

Kufanele kuqashelwe ukuthi paronit hhayi ngokweyame kunoma yimiphi imiphumela begazi. Lesi sici ikuvumela ukuba wandise nobukhulu bayo kwesicelo, isibonelo, ezindaweni ezishisayo efudumele, ugwadule noma amazwekazi ebandayo.

Ngokushintsha indlela yokwakheka fillers ungathola izinhlobo ezahlukene kakhulu paronita. Ngokwesibonelo, izinto ongasebenza ezindaweni aba nanezimo ezingagculisi hydrocarbon noma Izingxube yalo.

Ngeshwa, kukhona ukuntuleka paronita - adhesion okusezingeni eliphezulu, okungukuthi, Ngokunamathela evele uphawu. Lokhu kungaba sina izinkinga ukusebenza lapho ukuliqaqa noma silungisa izinto. Kodwa lokhu kusimo kalula ukulungiswa - kubalulekile ukubeka ungqimba graphite phezu uphawu.

Paronita yokukhiqiza inqubo ayiyona inkimbinkimbi. Ingxube oyifunayo injoloba, asbestos, fillers amaminerali nesibabule iqale sishisiswe izinga lokushisa oyifunayo, bese zavaltsovyvayut ku amashidi of ukushuba oyifunayo kusuka 0.4 kuya 6 mm. Umkhiqizo osuphelile kalula eliqinisekisiwe amandla - eligoqiwe ishidi neengcezu kungafanele sikhuntile noma ngezinye izindlela zonke ukugqashula kuyo.

Ububanzi paronita ngokwanele ububanzi. Ngomfutho ophakeme, bafakela i-paronit ishidi Iqala ukuba makhaza, ngaleyo ndlela egcwalisa izimbobo kwanoma yiluphi uhlobo.

Gaskets pon B kanye isetshenziswa amapayipi kanye nemishini ezisebenza umusi ayegcwele kanye amagesi ezahlukene imvelo (ezomile, inert, hlangothi). Njengoba paronit cushioning impahla pon A esetshenziswa kabanzi e compressors, aqoqa ukusetshenziswa ezimbonini amapayipi. izinga layo engashintshwa bedle uwoyela (kokubili ezinkulu nezincane nokukhiqiza) futhi konemimoya equkethe inani ngokwanele enkulu nitrogen ne-oxygen.

Ngakho bangakwazi uphawu izinhlobo apharathasi Metallurgical, amakhemikhali noma Petrochemical izimboni, usebenza nge izinto ngokwanele nolaka ashisa kakhulu (ziphuzo zazihluzwa apharathasi, scrubbers, ziphuzo zazihluzwa ikholomu, njll).
