Asbestos: Properties kunye Izicelo

kushishino Modern luphawulwa bume ndlongondlongo kunye namaqondo aphezulu. Ngenxa yoko kwafuneka ngokulitywina izixhobo ukuba ikwazi ukusebenza kwiindawo ngqwabalala. neemfuneko izinto ezinjalo ziyaphikisana yaye ezintsonkothileyo.

Kwelinye icala ukuba kufuneka zimelane nje thermally kuphela kodwa iikhemikhali, kodwa kwelinye icala - kufuneka babe bhetyebhetye yaye musa ukuluhlakaza mhlawumbi kwisinyibilkisi okanye esiphakathi.

Oku a ezinjalo lokutywina nobhaliso paronit.

Asbestos luhlobo noko entsonkothileyo leyo kumafa yayo khemikhali iquka:
- up to 70% ye-asbestos;
- malunga ne-15% iirubber zokwenziwa;
- malunga ne-8% ephilisa arhente ezifana nesalfure;
- malunga ne-15% ye fillers ezizodwa.

Oku kuphela ukwakheka paronita luqikelelo. Asbestos ekhoyo kukuninzi, kuvumela izinto ukubonisa amanqanaba aphezulu ukumelana thermal nemichiza. A irabha eyenziweyo unika ukuba bhetyebhetye ngakumbi.

Kufuneka kuqatshelwe ukuba paronit kuxhomekeke naziphi na iziphumo zebhayoloji. Olu phawu ikuvumela ukuba wandise yayo isicelo, umzekelo, kwi ekweleenjiko efudumeleyo, intlango okanye kumazwekazi ezibandayo.

Ngokuguqula isimo le fillers Ungafumana kakhulu ezahlukeneyo iintlobo paronita. Ngokomzekelo, izinto unako ukusebenza kwiindawo ezikhohlakeleyo, hydrocarbon okanye imixube yalo.

Ngelishwa, kukho kwakhona ukunqongophala paronita - adhesion eliphezulu, ie, unamathela imiphezulu uphawu. Oku kakhulu nzima ukusebenza xa sichitha okanye ukulungisa izixhobo. Kodwa lo nokubi lula mayilungiswe - kuyimfuneko ukuba bafake umaleko grafayithi phezu kobuso uphawu.

inkqubo yokuvelisa Paronita Akukho nzima. Lo mxube ezinqwenelekayo irabha, asbestos, fillers izimbiwa nesalfure kuqala itshiswe kwiqondo lobushushu oyifunayo, uze zavaltsovyvayut zibe amaphepha olulingana esifunwayo kwi 0.4 ukuya ku-6 mm. Le mveliso ogqityiweyo ngokulula iqinisekisiwe amandla - isongiwe iihafu sheet abafanele crumbled okanye ezinye iindlela aphule.

Scope paronita ngokwaneleyo ngokubanzi. Ngamandla, bafakela phezu paronit sheet Iqala ukuba flow, ngaloo ndlela agcwalise nasezimfanteni naluphi na uhlobo.

Gasket pon B kwaye lisetyenziswa imibhobho kunye nezixhobo ezisebenza kule zomphunga ifumile kunye neegesi ezahlukeneyo kwimeko-bume (owomileyo, egalelwe, cala). Njengoko paronit izinto ukunceda pon A lusetyenziswa kakhulu compressors, ihlanganisa ukusetyenziswa yoshishino imibhobho. umgangatho wayo akawatshintshi phantsi kwempembelelo oyile (zombini enzima kwaye ukukhanya) kwaye eliphakathi equlethe isixa esikhulu ngokwaneleyo initrojeni neoksijini.

Ngenxa yoko, zingakotshwa etywiniweyo iintlobo izixhobo metallurgical, zeekhemikali okanye petrochemical ushishino, ukusebenza kunye izinto ngokwaneleyo ndlongo kwiqondo lobushushu eliphezulu (izixhobo neyanamhlanje, scrubbers, umhlathi neyanamhlanje, njalo njalo).
