Iki Is "Ibidaboshye" ?

Niba warakoresheje agapfukamunwa, agatambaro ko guhanagura katose, cyangwa isakoshi yo guhaha, wakozehoumwenda utari uwo kuboha. Ariko dore uko bigenda: nta budodo bufite, nta budodo, nta budodo, kandi nta kuboha. Imyenda gakondo isaba kuzunguruka no kuboha—intambwe ebyiri z'ingenzi. Ubudodo butari buboshye bunyuramo byombi. Ubudodo (cyangwa plastiki yashongeshejwe) bushyirwa mu rushundura, hanyuma bugahuzwa n'ubushyuhe, gukururana, cyangwa kole za shimi. Mu 2022, Ubushinwa bwakoze toni miliyoni 8.29 zabwo—igice cya gatatu cy'umubare rusange ku isi. Ni urwego rukura vuba mu myenda, bitewe nuko rudahangayikishijwe n' "imyenda" na gato.

Meltblown: Akayunguruzo Kanini

Ihindagurika ry'ikirereBitangirana n'udupira twa polypropylene, dushongeshwa tugasohorwa binyuze mu tuzu duto. Udusatsi dushyushye twa 200-300°C twongerera ishongeshwa mu tunyuzi duto dufite ubugari bwa mikoroni 1-5 gusa—tumwe na mikoroni 0.5 gusa. (Umusatsi w'umuntu ufite mikoroni 70.) Utu dupira twiza cyane dukora inzira ikomeye kandi ifata bagiteri, ibitonyanga, n'utundi duce. Niyo mpamvu urwego rwo hagati rwa mask yo kubaga rugomba gushonga. Imbogamizi: ikora kuri metero 1-5 ku munota, yumva icitse intege, kandi igura $3,500-5,500 kuri toni—ihenze inshuro ebyiri cyangwa eshatu kurusha izindi zidashonga. Rero ntuzigera uyibona yonyine; buri gihe ni intwari ihishe iri hagati y'utundi duce dukomeye.

Spunbond: Ifarashi y'akazi

Spunbond kandi ishongesha polymer, ariko isohora uduce duto dufite ubugari bwa mikoroni 15-35—ikomeye cyane kandi ikomeye. Iyo irambuwe mu kirere kandi igashyirwa ku mukandara ugenda, urushundura ruhambirwa n'udupira dushyushye. Ingaruka: igitambaro gikomeye, kidacika, gikoresha umuvuduko wa metero 50-500 ku munota (kugeza metero 1.000 ku munota ku muvuduko mwinshi)—inshuro 100 kurusha isanzwe ishonga. Iyo mivuduko igura $1.700-2.800 kuri toni. Spunbond ni igitambaro cyawe cyo mu biribwa, igipfundikizo cy'ubuhinzi, igitambaro cyo mu nzu, n'imyambaro yo hanze y'igitambaro cyo kurinda. Irahendutse kandi irakomeye, ariko irakomeye kandi isa na pulasitiki—si ikintu wakwifuza guhanagura mu maso.

SMS: Turusheho Kubana neza

Ibicuruzwa bigezweho ntabwo bikunze guhitamo uburyo bumwe gusa. SMS-spunbond/meltblown/spunbond-isanzwe ihuza ibyiza byombi. Amakanzu yo kwa muganga akoresha spunbond yo hanze kugira ngo ahagarike ibinyobwa, meltblown yo hagati kugira ngo ifate uduce duto, na spunbond yo imbere kugira ngo ihumure.agapfukamunwa ko kubagani kimwe: urwego rwo hanze rwirukana amasasu, imyuka ishonga igafata virusi, kandi urwego rw'imbere rufata ubushuhe. Ndetse n'udupira twinshi tworoshye duhuza urwego rworoshye rwa spunlace rufite ishingiro rikomeye rya spunbond. Uburyo bumwe bufite intege nke; guhuza neza bitanga umusaruro udasenya.

Si ibintu byose bidafite ubudodo bigereranywa

IbidaboshyeNi ahantu hose - udupfukamunwa, udupira two guhanagura, amasakoshi, filters, amakanzu - nyamara abantu benshi ntibashobora gutandukanya meltblown na spunbond. None se ubizi: ukeneye kuyungurura? Genda meltblown. Ukeneye imbaraga n'igiciro gito? Spunbond ni igisubizo cyawe. Kandi niba ubonye SMS, ureba sandwich yakozwe neza. Izina rimwe "ry'imyenda", imikorere itandukanye cyane - n'icyuho cy'ibiciro inshuro eshanu. Gusobanukirwa izi nzira ntibizaguhindura inzobere mu myenda, ariko bizaguhindura umuguzi w'umuhanga.
